More Awesome Than You!

Okay, this is an experimental procedure that may or may not explode your neighborhood, currently in testing in AwesomeMod which will let you remove (and thus regenerate) Foreignia.

You Need:
1. AwesomeMod, latest edition.
2. Testing And Debug Commands Enabled
3. No one must be related to a foreignian. Never marry anyone from foreignia, or else that world cannot be nuked.

Step 1: Prepare the Neighborhood
Make sure everyone has returned from vacation and that no explorers are in any world that you will be keeping. There must be no foreign visitors either to or from a world that will have its existence status changed unless both will cease to exist.
Banish all foreign tourists by turning off Tourists and Explorers in AwesomeMod config and waiting for them to bugger off. Make sure they're really gone.
Then save and exit to the menu.

Step 2: Nuke Some Files
Nuke the following files in your save game:
TravelDB.package
*ExportDB.package

Step 3: Use AwesomeMod's New Command
Type "nukeworld X", where X is the foreignia you wish to incinerate and reset.

Does this mean you can have WA installed (and use the objects) without having travel destinations? Love this idea for "Terra Nova" type scenario - you can't go home!

No, it won't delete destinations, it will reset them: tombs, adventures will be reset to their original state.

You can alrady do this by using buydebug and looting the tombs. No, you cannot do this while ON vacation, and if you try, the game will call you a dumbass. However, this will let you reset any/all foreignias to their virgin states the next time you attempt to visit them.

Would "nukeworld foreignia" incinerate and reset all three vacation destinations?

No, you have to specify which Foreignia you want to nuke, or nuke all them one by one. The game does not possess a trivial means of detecting whether any given foreignia actually exists.

Will this delete any vacation home ownership, and should we just sell the vacation homes before attempting this?

You should definitely sell those first, yes.

I just wanted to say I noticed this was marked as experimental and I can vouch for it working. I backed up my game and followed the instructions and successfully reset China. I was a very happy camper.

So thank you for making my life just a teensy bit better!  :D

Will this affect any relic collections, etc. that a sim has stolen/retrieved from foreignia for their own personal collections at home?

No, stolen relics and other things are properties of the sim's own personal data, and not a product of foreignia: If you pack up and move the sim to an entirely different neighborhood that never had a Foreignia, that data would remain intact. Nuking Foreignia similarly has no such effect.

Any chance that this works for the University sub-hood? If so, what effect (if any) does it have on social group standing?

I'm trying to reduce the size of my save files to reduce the frequency of Type 12 Errors, which strike with alarming regularity in OS X. (At some point, running TS3 without resorting to Boot Camp became a world of pain; I was able to reduce random CTDs by turning down my graphics settings, but whenever the game runs for too long, a Type 12 causes game-save attempts to fail.)

I have no idea what would happen if you tried this on Uniland, since I don't have it installed. Assuming it is an entirely self-contained mini-world with little to no contact with the main one, it PROBABLY will work. Social group standing is probably intrinsic to the character, if it persists through a neighborhood move as well.
