Yea iam trying to do a lobby-browser kind of thing. I want the host to open a lobby if he wants. The game is listed in the lobby-list (that part is working) and i can also join with the second player. The problem is that i dont know how to sync the lobby-widgets. (Currently both players are in the same lobby but have their own empty player-slots).
EDIT: That sounds kind of like what iam trying to do, do you have a screenshot of the join process for me?
