form arms crashes a game

I have had a lot of games crash on me and then I stopped forming armies and the game never crashed any more.  With the .70 release, I played a multiplayer game and I started forming armies again.  At one point, I could not select my arm and tell it to move.  Then the game crashed.  I get no message the game just closes.  Is there any logs any where that I can look at to see what the issue might be?
