So i'm playing as cravers and i've jsut started, on turn 13 i've sent my scavanger2 fleet [9 ships] to invate a minor faction's system, because they have hyperium. Anyway i go to next turn, 14, the fleet arrives, i declare war, i siege, i invade without seeing the battle i click fight it's like 72 soldiers vs 40 or 36 i click fight and the ui crashe/freeze but the sound after the ui crash/freeze is the sound you get after victory. I've closed the game and tried 12 freaking times ... 12 times! And i always get a crash! What gives? I have a lot of hours ingame and not a single game or gaming session has gone by without a single crash. :(

Help!

Update: Moved the fleet around for a few turns, the fleet was back at the same minor faction system at turn 22. It still crashes on invasion. That game is unplayable. Would have been a huge advantage to get a hold of that particular system early.
