So I was in 2 games at the same time.
I disconnected even though my internet was fine, so I quit the game and tried to reconnect, but the option never came, the client pretended I was never in that game at all, so I que'd up and actually started another game and I was for a moment, in two games at the same time. op.gg won't even load either, so I don't know how it looks.
Atm, I haven't lost any LP from it, and it doesn't show up in my match history, which is fine, I'd rather not lose LP for a client issue anyway. This was on my smurf account, btw.
