Weird Champ Select Bug?

So I had queued up and got a game, then suddenly it went back to the Home Page. I thought someone had dodged but I thought it was strange that it wouldn't put be back in my lobby, then when I hit the play button it brought me back into champ select, where it was the ban phase. Neither me nor my teammates could select a ban, as there was a pop up saying something like "there was something wrong with the champion you selected please try again". And so it timed out and I was stuck in the black screen with 0 until I closed the client. Now I have a dodge penalty.
