Sommerswerd...this will happen lots of times during a pitboss game. The game is hosted in a computer in my house, instant powercuts, internet failures, random computer reboots, people exiting to desktop etc...are causes for the game to come down from time to time.
So when you see it down...be patient I will put it back up at first chance.
Nothing to do with 12 people on Hamachi btw..
