[URF] Leaving Queue Involuntarily

Playing URF with a friend. Get through bans and picks and lock in my champ. The queue then drops and we are kicked from lobby. When we go to queue for another it then tells me that i have to wait the standard 6min until i can queue again due to leaving the match. This has happened twice now so i thought i would report it as a bug. And yes i am 100% sure i locked in, I have been keeping mental note since the first queue drop.
