Bug report: Msg ¨do you want to finish what you where doing?¨ after getting kicked from the game

I don't have any screenshot, but i got kicked out of champ select by a screen telling me that an active game was found and asking me if i wanted to finish what i was doing or not with a 30 seconds timer. I still had champ select music playing and clicked yes, wich putted me in queue and i eventually rejoined the same lobby i was in (wich was bugged, there wasn't any connection to the others and i couldn't select a champion).

So anyone have experienced
