I started playing co-op with my friend today and found the game crashes occasionally when I try to alt-tab out of the game. I started playing by avoiding minimizing the game and half-way through I got an error that said something along the lines of 'dropped due to a bad connection', and lost our game progress again. Neither of us have a wireless connection and have fairly stable internet connections.



Could this be something on my end? Is it going to be possible ever to rejoin games or save a co-op in progress?

Playing while knowing you could lose it all in an instant is pretty miserable. Let me know if there's anything I can do to make co-op more reliable.
