When me and my family were trying to play this on new year we had a problem where not everyone could join. We had 6 players and when the last one was trying to join it froze at the load screen and got stuck there. So my sister disconnected and the other player could join but when my sister tried to join again the same thing happened to here stuck at loading screen.

Is there a bug or problem where 6 people can't join a local game or is that meant to be? Being only 5 players and one Ai?
