Hey...I just played a game of GB and while myself and 3 others were playing the game said quitting as it was out of sync
What does that mean?
A multiplayer game is played by receiving 'packages' of data from your host. those packages keep your game in line with the other players. If one or more players fail to keep in line, the game goes out of sync (short for 'out of synchronization' or something). It means that you actually get multiple games that play out differently, since the players that went out of sync will be dropped.
it's a common problem; not really a bug
