[Client] Champ select

I was in normal draft champ select and unable to ban a champion. I'm not sure if it was lag (internet is working fine) or if its a champ select problem but after the time got to 0 it still made the count down noise for another 5 seconds before exiting and putting me in my premade lobby. My duo partner was stuck in champ select and had to quit league to get out of it.
