I did so, and you were right, problem gone. Thank you very much for the speedy reply.

Okay, I'm getting a jumpy error thing; the sim starts an interaction and either the error window pops up or she just stops doing it. It seems to happen with romantic interactions, but then I think it happened once when she was just telling a joke, so maybe not. It seems to only be applying to this one sim, but I haven't actively tried to get it to happen to other sims. So I'm wondering if someone could give me a probable cause and save me a few hours.
It says it's error 552, and I've included the error log. As far as I could tell, it started after I downloaded some of Rufio's hacks, but I could be forgetting something else that I dled at the same time; I tend to be stupid like that. The ones I know I downloaded just before this started are:
bookshelfhackseasons.package
servosdontsleep.package
alienpregnancyforfemales.package (and yes, I remembered to take Smonaff's version out)
nostealfromfriends.package

I guess the most likely thing is just that one of them is conflicting with one of my older hacks, but I don't want to spend forever doing 50/50 tests unnecessarily so I thought I'd ask first.
Oh and I have EPs up to Seasons except Pets, and no SPs. Thanks in advance.

Edited for link fail.

So this stuff is definitely of interest to me, because I'm on a Mac and am thus dealing with the file limit. I raised it, but it's refusing to be raised any more and this is frustrating to my custom-content addicted self. Anyway, I have a question.
Basically I don't appear to have a TSBin, CSbin, or Support folders, all I have is TSData. Since it's been this way every time I've ever installed Sims on any computer, I assume this is a difference between the Mac and PC versions. (I also did a search to see if they were hiding in any sneaky spots on my computer, and it looks like that's not the case.) So I'm wondering if there's anything more in TSData that can be deleted without game implosion.
The specific thing I'm curious about is the N001, 2 and 3 folders in TSData>Res>Userdata>Neighborhoods. I have all the clean templates etc. installed, and N001 is renamed to prevent spawning townies. Since I've deleted these 'hoods from the game and don't ever plan to respawn them, surely it would be okay to delete them? Same question about the tutorial 'hood in the same place, as long as I never click on the tutorial button, the game shouldn't complain if I delete that, right?

Ah, okay. That makes more sense.
*backs up clean hood file multiple times* 

Oh, excellent! I thought I'd put some sims in college, but I must be remembering wrong. Thank you so much for your help, Mootilda, and everyone else who replied.

Okay, here's the file. I only have a university subhood, so unless the N004_Suburb001.package has something as well, that should be it. Thanks again.

Oh, and the pregnancy problem was caused by bad CC. *sigh* Back to sorting...

Okay, Mootilda, I've sent you a PM with the link. Thank you so much for doing this!

And Seelindarum, I'm going to try just removing all my CC and playing the birth again, just to make sure, but I think it's probably the character file issue. I was having the same problems with CC last time I had a birth, and it went fine.

Thanks for those directions, Seelindarun, that helps a lot.

Mootilda, that sounds like a good suggestion, other than my lacking that particular friend who runs Windows. Uh, unless one of you nice people would like to try. I guess I can just use Seelindarun's method and re-place all the lots manually.

Also, I was playing yesterday (I know I probably shouldn't be playing in a hood that is set for destruction of all characters, but I figure as long as I don't care about saving the progress I make...) and one of my sims was giving birth... but when it got to the "please wait for stork etc. etc." window, the window disappeared and the sim started the screaming animation again. It continued to loop like that. When I turned testingcheats on, it came up with an error message about the sim giving birth, and clicking reset just started the loop over again. I had to hide the game and force quit. Was this related to my character file issues or was a new VBT I should be worried about?

Okay. Well, since messing with the command doesn't seem like a good option for me, I'm gonna ask a possibly really dumb question. What I really want is to keep all the lots in this hood, decorated and placed as they are, that's all I care about. So if I were to make a new hood, with the same terrain, and then copy the Lots folder from the old hood to the new hood (and rename all the files with the right number, which I can do fairly easily)... would that do what I want it to? Or would it be a really bad idea?

Correct me if I'm wrong, but I'm fairly sure you can also just delete the CASThumbnails.package file (Wherever it is on PCs>The Sims 2>Thumbnails), and the thumbnails will regenerate automatically. That includes hair and clothes, though, which can be a pain.

Thanks for those directions, Pescado, but, uh, I don't really understand how to use the things you linked. I never mess with the command line. Any chance someone could give me a more thorough, dumbed-down walk-through?


Yeah, I know. That's the problem with being addicted to downloads... *sigh* But I'll manage.

Okay. I'm going to try and make this as succinct and clear as possible, but, uh, it's quite a tale. I'm only asking one question, but it kind of requires some background info. I'm not sure if it should go in here or the I borked it forum, but I guess I'll let someone else decide.

First, I'm on an intel iMac running Tiger (10.4), with Basegame up to Seasons, excluding Pets, with the latest patches as far as I know. I have a custom neighborhood, made using SaraMK's clean templates for the main neighborhood and all subhoods. (I only made a uni subhood, though.) I made some custom townies individually with testing cheats (spawned, not made in CAS) and a few families. Everything was going fine.
However, I have this re-occurring problem with corrupt files in my downloads that make my game crash when loading the neighborhood. When it crashes, character files are deleted. (If anyone has any advice about this problem, I would love to hear it.) But I have backups of my neighborhood, so I did some 50/50 testing, replacing the neighborhood files every time character files were deleted. Until I was really dumb, and, while testing, accidently forgot to copy the back-up folder rather than move it, and so my back-up got borked too, and I had no way to recover the character files.
(I currently have about 2000 potential corrupt files out of my game, btw. It runs fine without them, but every time I try to do a 50/50 test, it crashes with each half. I think it's something else that's conflicting.)
So since I now had 9 out of my previous 36 characters, I decided to just use DAC, delete the remaining character files, and begin re-populating the neighborhood, since I did a lot of work arranging lots in my hood and didn't want to start completely over in that regard.
However, I now am hearing that DAC leaving dangling SWAFs etc. and that this is a bad thing. So is there a way to delete all my characters correctly... without SimPE, and without just starting a new neighborhood?

...I think I did a bad job of being succinct.

(ETA expansion pack info, just in case.)
