On all my saves the game crashes with a windows message. Starting a new campaign works fine. I have come quite far in the game. (Needler gun and hercules) These are saves I have previously loaded without problems.
I assume I won't be able to play it anymore, which is a shame since it is the best UFO game I've tried so far, and the only I've played without tactical saving. I guess I could try it on hard instead, but I'd expect it to bug out like standard did.
