[endgame]

I'm almost certain this has a chance of being repaired, but with the side effect that the faces will not be retained. There's a file that can be renamed, but I don't recall it right now. I'll do some searching, but I think it's along the lines of faces.dat or facegen.dat

I'll post if I turn it up. Sorry you're having this problem. Almost nothing is more frustrating than not being able to load a game you've been playing for some time.
