I was winning a league match, ranked, and the game froze my entire system, to the point I had to restart it.

It's never happened before, but now I'm scared to play because it gave me an automatic concede on my coach.

I have reports and a screencast to show. I would like to know what the problem is.

I have a good PC, so it's definitely not my system that's the problem.
