Off and on through the months, I've read about end of turn, crash to desktop issues. Well, it just happened to me. A well developed game of many, many hours, and at the end of the turn, pressing the next turn button results in a crash to desktop. What could be the cause of this? I tired different save points with no luck. It's very discouraging, to say the least, not being able to continue this game. Why would I want to start over with putting a bunch of effort into a new game, with the thought that it could happen again?
