I have submitted the bug report: 500973
I have a game (www.ball3d.com). When some players create a server with, let say 8 slots, then in the server list it always says 1/8 (so the number of players is not updated). For most players it’s working fine.
Recently I have noticed that it is not working for players who had to do port forwarding in order to make the game works.
Did you notice this for your games? Any way to get around this?
