Game crashed, only on my team and lose

Im playing with friends and we're all together, we are winning our game about to win it soon and all of a sudden 3 of our computers, including mine, crash and says we need to reconnect. We hit reconnect and it completely shuts down all of our computers and lap tops. We have one friend in the game and they pushed and won before we could all get back. I don't know if it's a bug, but I smell hacks.
