Well, apparently there is going to be a bug fix and lobby fix update today. I'll wait and see if that does anything.
Update: When I joined a lobby, the host left, I became host and the lobby successfully showed up on the lobby browser. I can not update the systems though. When I do change the system, I can't change anything else. The lobby will show the previous system and the previous # of players. Server browser no longer updates when I change systems.
