While I continue to not have a ShuffleIT forum account because I can't be bothered to sign up, I'll post here.
It looks like this unable to confirm e-mail account issue is playing havoc with the lobby. I have noticed that when I tried to Quick Match or Bot Game, it would tell me I couldn't host a game, but then it turns out that it still created a game anyway, but left me out of it. I found a number of games I was apparently hosting from a few hours ago, which I can only think of as coming from this.
I managed to clean up my fake games by joining them as a spectator, joining, kicking any poor soul waiting for a game, then leaving. I couldn't actually play the game because it still wouldn't let me host.
It seems like the lobby is currently filled with an enormous number of these fake games. Might be worth purging the lobby of duplicate hosted games, it's really difficult to find a legitimate game right now.
EDIT: Of course it's only difficult to find a game because matchmaking isn't working because e-mail confirmations aren't working.
