GAC problem

I hit this one today as well.  I was on my way to a win of the battle when it got hung.  Even when the battle timed out I could not submit the loss and the progress (2 kills) that had already been made.   As previously mentioned I was forced to close the game and the loss was taken implicitly with no progress recorded.   

Fix your game CG!

This is an old bug that has never been fixed. It happens sometimes and yes, the only solution is to force close the game and take the loss on whatever battle you were doing at the time.
