There seems to be a problem starting 9 and 10 FFA games where they freeze after clicking start game showing the commanders. When we reconnect everyone is back in the lobby again and it's generally chaos as some people reconnect, others drop out, etc. Sometimes the game will start on the next attempt... other times we just have to abandon the game. EDIT: This seems to be new with 71729.
Happens a lot in ZaphodX's streams I watched, and I tend to think it's because the numbers of players + spectators is > 10 I can't vouch it's the cause, but there were previously issues (maybe still is, didn't check) with 10 players FFA and spectators, because spectators were reserving a color, and there were not enough available colors for the players.
