Same issues here.
It looks like once you join a game, one of the players disconnects, ai doesn't take over, and the wait time doesn't disappear after the time is over. Or maybe it's just one of the players failing to connect to the game. Either me or another player is constantly failing to connect to the games.
The other two/three players are just stuck in the game. When they reconnect, it takes them back into the stuck game.
If you decide to leave the game, it costs you elo and stars. But there is no other way to leave the game other than to quit it appears.
I will stop playing Catan Universe until this issue is dealt with. The game is literally unplayable.
