Got leaverbuster because i couldn't reconnect

So i was on a coop vs AI queue set on beginner to test if my ping was high so it happened to be really high and i couldn't move my champ and minions wouldn't die. So i exit the game to try and reconnect. After 5-6 mins of loading, i expected the reconnect button to appear but instead it said "skip waiting for stats", so i literally couldn't reconnect. I go on blind pick and the game says "These players are not ready: Roshies". I understood that i was still in game but i couldn't reconnect since it never appeared. I woke up the next day to find a 20 min leaverbuster for 5 games. Please fix this bug and i obviously don't deserve this leaverbuster. Why would i leave a coop game? [sg-janna]
