My game keeps crashing with an unspecified error message when I end turn. It's late in the early campaign, at turn 265 after the Timurids have invaded. The game keeps crashing during their turn or sometimes at the rebels turn, but I can't get it further than that. I don't know what to do to fix it. I've already deleted the virtual store and turned off daylight savings. Anyone have a similar problem and how did you fix it?
