Lobby bug, no champion selection

I was waiting in queue for a game, joined a game, banned a champion, then got a message saying i disconnected from the server, though my internet was fine as I had another page open working just fine. It said it was trying to reconnect but i clicked Exit Instead. When I reopened the league client I was back in the lobby and people were choosing champions, but when it came to be my turn to select my champion i had no options, all the champions were gone and I couldn't click around to get one, there was no champion selection. I then was forced out for not picking a champion and given a queue timer for dodging.
