Re: Lots/Sims won't load
@gemjasmine This happens occasionally and is a sign of save corruption, although it can sometimes be fixed. Please start by deleting the five cache files in your Sims 3 user data folder (the one in Documents\Electronic Arts). These files should be deleted regularly anyway; while troubleshooting, delete them every time you quit. For reference, they are:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
Try to play again, and see whether the problem recurs. If you want to save, use "save as" to rename the save, so you'll still have the original as backup. If the lot fails to load again, quit without saving, delete the cache files again, reload, then go to Edit Town, evict your sims, and place them back in their house. They'll keep their jobs and relationships but lose their promised wishes and opportunities. Afterwards, let the game clock run for a couple in-game minutes, "save as," quit, reload, and see if you can play forward without any issues. Let me know either way.
