Did you try removing all CC to make sure that’s the issue? If so, sort the files by date created and segregate the ones you’ve downloaded since the last time your game loaded properly, and start there!
I’m doing that right now. The trouble is figuring out at what point my game crashed. Because it’s a little difficult to wait 2-3 hours at a time just to wait for a crash…
