Re: sims 3 a serious error has occurred
@willowcloud9 It sounds like the instance of Monte Vista may have been corrupted, unfortunately. Adding ErrorTrap and Overwatch could help, but there's no guarantee: the world might be too corrupted to recover.
Be sure to delete the five cache files in your Sims 3 folder (the one in Documents\Electronic Arts). These files should be deleted regularly anyway, and in particular any time you're troubleshooting. For reference, they are:
- CASPartCache.package
- compositorCache.package
- scriptCache.package
- simCompositorCache.package
- socialCache.package
Please also delete any files in the CurrentGame folder in the same place. This folder should always be empty unless your game is open and a save is loaded, but sometimes data doesn't get deleted when you save.
If you don't want to add more mods, or those two mods don't help, try recovering the automatic backup save. Go into Documents\Electronic Arts\The Sims 3\Saves, and you'll see a folder for your current save and another folder with a .backup extension; this represents the second-to-last time you saved. So if your save is named Monte Vista, you'll have a folder labeled Monte Vista.sims3, and another labeled Monte Vista.sims3.backup. Delete the .backup extension and rename the save (e.g. Monte Vista 1.save), and it should be available to load from the Main Menu.
If this backup save doesn't load, there are a couple other approaches, but there's no guarantee they'll work. Let me know how things go.
