I didn't save that game or anything, I can do that, if that happens again and I can't see any reason why it wouldn't. I've played only couple of games and I think all games have had this thing happening.
This rune guy in CM-chat said it could be that my 3d-card has ran out of some memory. I have TNT2 (m64) (with 32mb I think..) Other: c466@525, 196mb.
