This is the one known-about and unfixed bug. I'm posting this here so that no one else will...
Either way, in Beta5.2 I have limited the number of players to 10 ( I think ). If anyone hosts a full house and the bug still arises, please inform me either here or via email, and I will reduce the number of players to 9. ( This process will be repeated until we stop this bug from arising or it seems to fix itself during one of my code rewrites. )
