[client]? Unable to lock in champion. Kicked from game for not selecting

I just bought . tried to play him in a bot match to feel him out. I picked him quickly and hit lock in. a while later i looked and saw the button was greyed out, but it still said I was picking, even though 's picture was there. I was kicked from the game for not selecting a champion when the timer ran out. Writing this while I wait down the timer.
