Playing ranked game, about halfway through firewall picked up unauthorized attempted to access my system.
Then 5 seconds later, game screen closed with a message saying no game found. Promptly sent back to the client home page, as if nothing happened.
Game was not even over, sure we was not in best position to win it (still had fully intact base inhibs towers etc), but i check history and it went down as a loss.
(do note, this access into my system ONLY affected the game nothing else! Also game recording showed my team players had froze seconds before it just said defeat, but enemy team was still moving around and getting cs etc then defeat popped up out of no where for no reason at all)
