Create-A-Style not working

[vhanster]

For some reason, I can no longer access the Create-a-style tool in my game. Everytime I try to edit styles, I get this "materializing materials" loading screen, and then it stays like that forever until I end the game's process. Dunno if this have something to do with the massive amount of patterns I downloaded recently, though I'm not keen on doing a trial-and-error to see which files are causing this problem. Any help?

This is indeed caused by a broken pattern. I suggest using the 50/50 method to quickly figure out which one: Game Help:Finding Problem Custom Content - although, of course, if they're sims3packs, then you don't have a non-arduous option I'm afraid.
