[Client] Cannot select Champ in 3v3 Flex

Upon accepting into champ select, my screen will not show my roster of champions, nor will it display any of the bans as they come out. I would post a screenshot, but it didn't occur to me at the time. Tried it twice which has now resulted in a 30 min ban. I will try another queue after and see what happens. Since it happened twice, I reckoned it was worth reporting.
