I'm not sure if ^this^ was the problem necessarily, but I'd say it is, since I've only had it happen in this specific scenario. So, we were playing 3 people. It was this guy's turn. He checked the barrel to see what colour the shell was, then used his adrenaline to steal a saw from another player. After sawing the barrel off, he froze for a few seconds before disconnecting. After that, the game crashed entirely.
