Before you load go to options, and select cloth map only, and then load the game. That may get you quite a bit more play time, depending on the reason of this crash. At any rate, I noticed myself when I cranked up a game that was over 300 moves or so in that the game sort of hung. I say, sort of, because instead of a CTD or something like I'd have gotten before the game got rid of the loading dialog and sent me back to the main menu - with one unfortunate caveat. None of the menu dialog was there, but I did get to watch that whole town coming out from behind a mountain thing. Cloth map got me some joy, I was able to get in long enough to smash the opposition, and isn't that what everyone really wants?
