Champ Select Bug

I was playing Nexus Siege. I was in Champ Select and picked Tristana, but her image did not appear next to my name. After the time expired, I got a message saying there was a problem selecting my champion. I tried picking Varus, but I got the same message. Then it kicked me back to the client with a message saying that I dodged the game. I obviously didn't. Now I'm blocked for 5:00 minutes from joining another game.
