Bugs

I was made to afk due to a pc problem and I was given 20 min ban. Moreover, in then second game i waited 20 min with a friend and when all 10 accepted que the champion select screen went black (not my pc screen, only league screen) and I was unable to pick a character or chat and i was made to wait again 20 min +5 for dodging que. This is what makes people to quit this game i waited 45 min for a game.
