[Client] Champion Select Covered by Lobby Screen

I've had this happen at least once a day (if not once every 2 days) and today (9/24/14) it has happened 3 separate times.

1. I make a game and invite friends.
2. Hit Play
3. Accept Match
4. Instead of Champion Select, it simply takes me back to the lobby screen, with champion select noises in the background. I cannot select a character, and I cannot tab out to make it fix. I can literally start a new game right there in the lobby screen while Champion select is happening. I have no idea what is causing it or what to do but it is causing me to sit through 5-10-15 minute dodge timers and it's getting a little annoying. I'm even afraid to try to play ranked because I don't want to lose LP because I can't select a champion.
