Kicked out of champion select

Was in the champion select for a ranked game, I was banning and I had 10 seconds left on the clock. I selected mundo and boom got kicked out of the game. Figured someone dodged, went to re queue and It said I had dodged. Well normally this wouldnt bother me but Im in my promos and it gives me a lost game for it. Dont ever remember this happening before but you shouldnt be removed before the timer is up and get flagged with a promo loss.
