I've been dealing with this for such a long time, and when the problem stops all of a sudden the latest lobby update seems to break it again.
Currently, and quite often, I can not start a custom game, and it appears that there are no games to join. The reason that I can not start a custom game is because EVERYTHING from the mod list, including vanilla FAF is missing. The only thing that I can do is search for a ranked game.
Another issue that I am having is that I frequently lose connection to the FAF client, and must restart it.
I understand that I am supposed to post logs, but I just tried to do that and can't since I'm actually typing this up in the FAF lobby, and can't access the files when the lobby is in use. I will update this with the logs shortly. PLEASE fix this, or tell me what I can do.
