It's great that this issue was solved, but why does it occur? (Just curious.)

Please look at the attached error logs, since I have no idea what's wrong (other than that there's a crappy GUID somewhere).

Here's the situation: Samson Vaughn, started doing Tai Chi at my direction. He got naked (which I didn't expect, but is probably normal, considering hacks), but then he started getting a "Crappy GUID Error" in the Temperature Controller. Cancel and Reset didn't work, so I had to Delete. Then I canceled Tai Chi, and he remained nude, and suddenly he (not the Temp Controller) started getting a "Crappy GUID Error." I suspect this second error is due to my deletion of the Temp Controller.

Potentially relevant information: He just got back from vacation (Far East). The return from vacation was buggy: When he (the whole family, actually) got back, the shuttle tried taking them again. I canceled the action from all three Sims, and eventually the shuttle left anyway. When it did, it took me (with no Sims) to the hotel lot where they had stayed. I exited to Neighborhood without saving and reloaded the home lot. Fortunately, they were all there. Unfortunately, the shuttle came again. I got rid of it with Force Error -> Reset. I don't know if that's relevant, but it was so recent, I thought I'd mention it.

Thank you!

How did you bring them over?

I've never touched insim, so I don't know what it can or cannot do.

  The way you spelled it, "inseminator," makes it sound like the program causes pregnancy.

What's unusual is that two werewolves are showing up regularly. A second werewolf is sometimes called to a lot, but it's uncommon. Normally, it shouldn't happen nightly. On the other hand, maybe the dogs just like your Sims.

As for the abductions, maybe an abduction hack crept into your game? Or maybe it's just sadorandom.

I saw through this immediately. (And by 'this' I mean the title if the thread.)

Forgive me for my incompetence, but what is the 50-90 rule?

What is the Intelligence career?

It most certainly is, and I owe him plenty of "BHAAAA"

Well, now THAT would *technically* be illegal, if  the previous owner still plays the game. (If not, I think it's legit.) Of course, many of the users on this site pirate the games, so using someone else's disk to install the game is hardly as bad. I personally refuse to buy any more Sims 2 games after having plagued myself with SecuRom. I myself am debating pirating the game, but I won't get the game at all until most of the borkenness and irritations have been fixed.

Wow, this is the first feature of FT that has actually appealed to me. But EAxis is too late; I have a hack that already lets me age up townies (so long as they're best friends with the asking Sim).

If you fixed the fire errors, the lot might be safe to play. If you still have the error logs, you should post them so we can look at them. (And by "we" I mean someone that can actually decipher it - not me.)

But don't take my word for it - wait for someone more awesome than me to comment.

Did you delete the groups.cache file? (It seems obvious, but I often forget to try that.)

I do, and that explains it. Thanks!

Maybe next time I download a hack from MTS2, I'll read the thread, the way I do here.

That prevented the phone error. I got to the menu (same as with computer). I still got an empty dialog box. when I clicked yes, the transaction went through, and I got an empty Info box (presumably saying Congratulations, or something).

I can live with empty dialog boxes, though.
*Steals a Goat with Goatnapper, then sacrifices it to thank Pescado*

I am having trouble purchasing a vacation lot.

When I try to buy one via the phone, an error message pops up saying something about "No parameters." (Error log attached)

When I try to buy via the computer, I get to the menu showing which lots are available to purchase. I select a lot and click the checkmark, and an empty dialog box appears with two choices: Yes and No. At this point, I was thinking it was probably asking for confirmation, but before I chose "yes," the box vanished. (I think it defaulted to "no.") However, there was no error log.

At this point, I saved and exited, then came here to  post. I think there are two separate, but related, problems. I'm going to try a binary search, although I think the phone issue may be related to the phonehack. Or to the fact that this is an empty neighborhood, and I'm allowing the game to create NPCs as I go -- I think this may be related to the problem because the error report mentioned "employee creation" or something like that.

Unlike this house, I am not awesome. Where do I install this file? (When I put it in Downloads, the house didn't appear in the Lots and Houses Bin.)

Thanks, everyone! I've edited the first post with all of your suggestions.

I wasn't watching very closely, but one of the Sims was continuing to eat once the Hunger bar was completely full.
I've seen this with other foods, too, but no specific anecdotes are coming to mind right now. I think one of them was Baked Alaska, but the Hunger bar may have been low enough to warrant that anyway.

I have posted an update for the Tutorial on how to create Clean Custom Neighborhoods and Create Townies. It is here: http://www.moreawesomethanyou.com/smf/index.php/topic,10798.0.html

I have posted an update for Bon Voyage here: http://www.moreawesomethanyou.com/smf/index.php/topic,10798.0.html

First, a BIG thank you to all the following people:
•   Jordi, for the Seasons version of this walkthrough, which I mostly just copy-and-pasted, then edited from there. Most of these words are Jordi's!
•   SaraMK, for the empty templates for Uni through Seasons.
•   Argon, for the empty template for BV (buried in Sara's thread) and for the NPC generator [Make Vacation Sim (Local)] fix.
•   JM Pescado, for the no respawn, no regen, and antiredundancy hacks. Without these, this process would be mostly useless! Pescado is also the owner of the site.
•   Everyone who offered suggestions to make this tutorial better.
•   Anyone else I may have forgotten (for which I deeply apologize - point out the omission, so I can add you to the list).

This tutorial will explain how to create a custom neighborhood with unique townies and NPCs, rather than the default Maxis ones. To make sure these new Sims are as unique as possible with skintones, clothes, hair, eyes etc.., you can follow the links/tutorial by Zarkan.

0: Mods
I recommend the following mods to prevent extra character files from cluttering up your game:
•   Anti redundancy
•   No townie regen
•   No stray respawn
•   No SS respawn* [You can get these 4 hacks from the FFS Hack Directory]
•   No dormie regen* [You can only get this one from the DC]
A teleporter [look in Peasantry or MTS2] is also handy.
In addition, you need the Make Vacation Sim (Local) fix to make Vacation Locals correctly.
(* You only need these if you have Uni, of course.)

1: Preparing - cleaning out templates
Go to where you have installed The Sims 2. This will be C:\Program Files\EA Games\The Sims 2\ by default.
Browse to the UserData Neighbourhoods folder: The Sims 2\TSData\Res\UserData\Neighborhoods
Rename the "N001" folder (to anything, such as "N001-bak"). This prevents the default townies from being created in new neighborhoods.

If you have Pets, go to your Pets folder (C:\Program Files\EA Games\The Sims 2 Pets\ or wherever you installed it). Browse to the Neighbourhood template folder \Pets\TSData\Res\NeighborhoodTemplate\P001 and do the following:
•   Back it up. I just zipped the entire folder so I can restore it if the Pets patch comes around, or if I ever want it back.
•   Do further cleaning: delete now-unneeded the \Character, \Storytelling, and \Thumbnails subfolders
•   Replace P001_Neighborhood.package with an empty version. This prevents the standard Pets and Pet NPCs from being added to every 'hood. It also prevents the two families from magically appearing in your new 'hood's family bin.

If you have Seasons, go to your Seasons folder (C:\Program Files\EA Games\The Sims 2 Seasons\ or wherever you installed it). Browse to the Neighbourhood template folder \Seasons\TSData\Res\NeighborhoodTemplate\ and do the following:
•   Back G002 up. I just zipped the entire folder so I can restore it if a Seasons patch comes around, or if I ever want it back.
•   Do further cleaning: delete the now-unneeded G002\Character, G002\Storytelling, and G002\Thumbnails subfolders
•   Replace G002_Neighborhood.package with an empty version. This prevents the standard townies and Seasons NPCs from being added to every 'hood. It also prevents the two families from magically appearing in every new 'hood's family bin.

If you have BV, go to your Bon Voyage folder (C:\Program Files\EA Games\The Sims 2 Bon Voyage\ or wherever you installed it). Browse to the Neighbourhood template folder \Bon Voyage\TSData\Res\NeighborhoodTemplate\ and do the following:
•   Back V001 up. I just zipped the entire folder so I can restore it if a BV patch comes around, or if I ever want it back.
•   Do further cleaning: delete the now-unneeded V001\Character, V001\Storytelling, and V001\Thumbnails subfolders
•   Replace V001_Neighborhood.package with an empty version. This prevents the default NPCs, tourists, and locals from being added to every 'hood. It also prevents the Traveler family from magically appearing in every new 'hood's family bin.

If you plan to use any of the premade subneighbourhoods for your new 'hood, now is a good time to clean them out as well. If you are going to use an empty terrain file for the subneighborhoods, you can skip this step. (You can use premade sub neighborhoods for some sectors and empty terrain files for others, of course.)

•   Unzip the downloaded file, which is D001_Neighborhood.package. Place this into the D001 folder.
For the Universities:
•   Open C:\Program Files\EA GAMES\The Sims 2 University\TSData\Res\NeighborhoodTemplate\
•   Make a backup of the U001, U002, and U003 folders.
•   Open the U001 folder. Delete everything inside the Characters folder and delete the file U001_Neighborhood.package
•   Unzip the downloaded file, which is U001_Neighborhood.package. Place this into the U001 folder.
•   Repeat steps 3 and 4 for U002 and U003
For Bluewater Village:
•   Open C:\Program Files\EA GAMES\The Sims 2 Open For Business\TSData\Res\NeighborhoodTemplate\
•   Make a backup of the B001 folder
•   Open the B001 folder. Delete everything inside the Characters folder and delete the file B001_Neighborhood.package
•   Unzip the downloaded file, which is B001_Neighborhood.package. Place this into the B001 folder.

For the Vacation Destinations, you have to download the file from this post.
•   Open C:\Program Files\EA GAMES\The Sims 2 Bon Voyage\TSData\Res\NeighborhoodTemplate\
•   Make a backup of the A001, T001, and M001 folders.
•   Open the A001 folder. Delete everything inside the Characters folder and delete A001_Neighborhood.package
•   Place the downloaded A001_Neighborhood.package into the A001 folder.
•   Repeat steps 3 and 4 with T001 and M001.

2: Creating a new neighborhood
Open The Sims 2 and start a brand new neigbourhood in the normal way. Do not create any Sims in CAS yet!
After creating this 'hood, alt-tab or exit to Windows and check your new neighbourhood character folder (If this is your first custom neighbourhood, this will be My Documents\EA Games\The Sims 2\Neighborhoods\N004\Characters\). This folder should be empty. If it is not, you have not done step 1 right. You should probably start over at this point.
DO NOT USE THE DELETEALLCHARACTERS CHEAT! This corrupts the neighborhood.

3: Subneighborhoods
Adding a default subneighbourhood (universities U001-U003, downtown D001, shopping district/bluewater B001, or vacation destination T001, M001, or A001) will add a great number of default townies and NPCs, as well as some playable Sims. You can prevent this by replacing them with empty versions (follow the instructions above, in step 1), or by starting from an empty terrain file.
If you use the cleaned out templates, make sure you have also deleted the templates' character subfolders.

4: Populating the ‘hood
First, decide if you want to create all townies yourself in CAS, or if you want to batch-create them. Batch creation will lead to a balanced neighbourhood setup, but your townies will not have any custom clothes or make-up, unless you "de-customize" them. Theo explains the process here. They will use the default facial templates (or overrides, if any) and default name list. You can change the name list with Jordi's mod from MTS2. The thread there explains how to change the name list yourself.
The CAS method requires you to create townies yourself, and later edit them in SimPE.
There is not yet an easy way to make custom Pets into strays, aside from using SimPE.

4a: Batch-creating townies and downtownies
Create a Sim or family in CAS and move him in a lot. Immediately pause the game. Note: unless you had Pescado's No Townie Regen in place at this time the game will automatically create one townie.
Important: If you also want to fully customize your NPCs, buy the FFS Lot Sync Timer and use the Time Warp feature at this time to set the hour to 05:00 to prevent the paper delivery NPC from coming by while you're busy. If the clock approaches 08:00, reset it to 05:00 again with the Time Warp.
Enable the testing cheats in the console: boolprop testingcheatsenabled true. There are two ways to batch-create townies: the NPC and Townie maker ("Townie tree") or the mailbox. Both methods will work.
If you want to use the Townie tree, click on your Sim, and in the Spawn menu select the NPC and Townie maker. This looks like a dead willow tree before Seasons or like the Repoman's gun post-Seasons. Choose "Create townies", and select "townies" again.
If you want to use the mailbox, shift-click the mailbox and select *DBG - FORCE Create Townies, and select "townies" again.
Townies will now begin spawning. At first the thumbnails will show NPC portraits, ignore this. It will report when it is ready.
Save the game and check the character folder when it is done, you should now have 32 Sims: your CAS Sim, the initial townie (unless notownieregen is in place), and the ~30 created townies.
This number seems to be increased post-Pets: I ended up with almost 50 townies by batch-spawning them.
Downtownies can only be created using the Townie tree. First, select Switch to make downtownies (not needed in Pets), then "Create Townies" again - select "Downtownies" this time. Downtownies will begin spawning, without portraits in the upper right. Again, the game will report when it is ready.
From the mailbox: *DBG - FORCE Create Townies - "Downtownies"
Save the game/lot now.

4b: Creating custom townies and downtownies
In CAS create as many townies as you like, of whatever ages, genders, and using any content you like.
No need to bother with names at this time. I simply named them 1 to 8 for each group.
My own setup is the following:
Group 1: males -- create 8 adult male Sims
Group 2: females -- create 8 adult female Sims
Group 3: Miscellania 1 -- create 2 elder males, 2 adult females, 2 teen males, 2 teen females. Set the teens as children to any adult female.
Group 4: Miscellania 2 -- create 2 adult males, 2 elder females, 2 child males, 2 child females. Set the children as kids of any adult male.
This leads to 32 townies: 10 male adults, 10 female adults, and 2 of each gender of the other age groups. This leads to an average spread of ages and genders. But you are of course free to chose anything you like.
Move group 1 in a lot, and pause the game. If you also want to make your own NPCs, refer to the note above about the Sync Timer in 4a.
Buy the Ingelogical Teleporter Shrub or Painting (or another teleporter such as the inSIMenator module). I use the Teleporter Shrub in this example.
Select Sim 1, and make them a townie using the teleporter. Repeat this for Sims 2 to 8.
Using the teleporter, summon the Sims from the other groups you created, and move them in using the shrub. Then make them into townies.
You should have no playable Sim left on the lot after you're done. Save and quit the game, and check the character folder. You should now have 32 Sims: all your custom townies.
Now open SimPE, and select all Sim Relationships you see. Delete them if you don't want your townies to have family relationships with each other.
Start naming your townies anything you like. If you like, also give them skills, jobs, and gender preferences. Note that if you do not give them a job they will get a random one the first time they're loaded, and their skills will be randomized accordingly.
Save the 'hood file, and you're done.
Make downtownies the same way you did townies, only select Make me a.../Downtownie for them. I created just 8 downtownies in my game: 3 adults and a teen for each gender.

To make vacation Locals and tourists, you need to make the Sim into a townie first, then select "Make Into Vacation Sim>(type)>Sim Name" from the townie-making nerf gun. Note that that menu doesn't give the Sims' last names, so make sure you differentiate your Vacation Sims' first names in CAS from your regular townies. (Such as A1 - Asian 1 - instead of 1.)

4c: Dormies
*Please correct me if I'm wrong about method (a).

You can make dormies the same way you make townies. Using method (a)*, you have to be on a University residential lot when you batch-create the townies. A residential lot, not a dorm. Under method (b), you have to create the Sims in the Uni CAS (duh), then move them in to a residential lot and use the teleporter or townie tree/gun as illustrated above. Again, it can't be a dorm.

4d: Pets
You can create strays one-by-one with the tree, or you can create custom pets in CAS. Use SimPE to put CAS-made pets into the Strays family.

5: NPCs
Note: NPC creation using the tree may not work correctly in OFB, FFS, and GLS. This was fixed in Pets/Seasons.
If you don't care about customized NPCs, don't bother creating them. The game will make them as needed.
You can use the Townie tree to customize your NPCs.
Make sure the townie/downtownie switch is set correctly (townies for base, EP1, and EP3 NPCs and downtownies for EP2; the switch is not needed in Pets), and set your desired age, skintone, and gender settings. Then create NPCs one-by-one. Select 'keep' once one is created. Do not chose invalid combinations: nannies must always be elder females, headmasters are always male, etc..
As of Pets you can create individual NPCs again, and Grand Vampires (Count/Contessa) are now under the NPCs menu.
If you want to spawn the "special townies" Vampires, Slobs, Diva/Mr Big, set the switch to downtownies (not needed in Pets), and spawn the special townies using their menu. 'Keep' them once done.
You cannot spawn the (OFB) reporter "special townie" (one reporter will be spawned whenever the game needs one). The special NPCs Death, Mrs. Crumplebottom, etc. cannot be spawned as these are unique: the game creates them the first time a 'hood is loaded.

If you own the game, using a no-CD crack isn't illegal. It's only illegal if you didn't buy the game, but downloaded it or borrowed someone else's CD to install it.
