Client Crash

Basically, while playing the map 'ancient gifts' at about 2:45 hours in the game with 1 AI nearely defeated and another announcing an attack on one of my asteroids, the game warns me that a planet is under attack and then I get a black screen get a 'windows fiesta is trying to fix the problem' message then 'the problem could not be fixed, close application' I.E. A client crash, my best guess something in the AI, but I can't say for sure...thankfully I just saved the game before, but the crash happens every time when I load that save after about 2 minutes.
