Hi

I encunter a very troubeling bug: in skirmish mode, at some point i am just defeated for no reason and it occured in all my last skirmish games.
I really do not understand the problem and as a confirmed player i can tell it's not a normal defeat from rules so i am lost. I kept a save of my last crashing game and a screen capture.
If anyone here is able to help me, it would be super cool cause now i can just replay the campain mode (which work properly)
