Re: Corrupted files
@jeanmarie618 Please open Documents > Electronic Arts > The Sims 3 > CurrentGame and delete everything inside; this folder should always be empty unless you actually have a save loaded. In the same Sims 3 folder, delete the five cache files as well (again, if you did it previously):
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
Try to load your save, and if it works properly, let the game clock run for a few minutes, then use "save as" to rename the save, so you have a backup in case you need it later.
If the save is still borked, quit without saving, then inside the Sims 3 folder, open Saves and look for a folder labeled [your save name].sims3.backup. This folder contains the data from the second-to-last time you saved; if you rename it and delete the .backup extension, you'll be able to load it from the Main Menu. Delete the cache files and everything inside CurrentGame again, then see whether the backup will load. Again, if it does work, use "save as" and rename it.
Exchange items are not considered custom content by themselves, but cc can attach to Exchange uploads and then install itself in your game. Often enough the creator doesn't even know that their content has cc attached, so the "no cc" tag can't always be trusted.
The empty stage is a known issue, and the extra proprietors might be as well—it kind of sounds like something the game would do—but I haven't looked into that in particular. The easiest way I know of to solve the latter, at least, is with mods. Let me know if you use any or are interested in adding a few. You might well need mods to fix your save anyway, given the state it's in at the moment.
As for EA support, this isn't really the kind of issue I'd expect a support rep to be able to solve. Corrupt saves are more the purview of forums like this one and forums.thesims.com.
