Re: Sims 4 game crashing after exiting cas

@gracemking  Please test a few times in a row with no mods or custom content, as in, move the entire Mods folder to the desktop and delete localthumbcache.package.  If you get another crash, please run a dxdiag and attach it to a post.

If you don't get a crash, start testing your mods and cc, but don't just add some of it back, make sure you assign any content you've added to one of the sims you've created.  That includes any custom traits if you use them.  If you can remember which cc you had just used on a sim when the game did crash, even better—test that cc first and see whether the game crashes again.

There is, unfortunately, no way to find bad mods or cc without testing.  The only alternative is to clean out your current collection and stick to newly-downloaded content that's confirmed compatible with the current patch.
