Was trying to make an ice sim sculpture with my family. The guy being sculpted posed, the sculptor watched the guy, but no sculpture was being made. I couldn't cancel the interaction for the sculptor, and the shadows of the guy being sculpted's feet wandered off and made noises - when I checked the "sculpt ice sim" interaction again, there were two of the guy being sculpted - one a stranger one the original.
After quite a few attempts at resetting the sims, and still no luck, I decide to save the game and quit. However, when I click save + quit or main menu, nothing happens. I can't even just save - nothing happens there either.
Any ideas?
edit: Okay, my game's just screwed up completely. I can't enter buy mode or build mode, and my sim can't paint. Looks like it's just a massive corruption. Back to the beginning again then..
