Dark Star Thresh Just Cost Me A Ranked Game.

Yeah, what the title said. The support (who was Thresh) said it was his 1st time using the skin. A few minutes into the game, he disconnects. Apparently League crashed for him as he said later. But during the time he was gone, the ADC gave up 1st blood, and kept on dying. The other ADC got really fed, and then our Master Yi top laner started to flame us about being in Bronze and us sucking, then he began to rage and feed, and then afked for a bit too. By the time Thresh reconnected, the enemy team was really fed and we had lost all our T1 and T2 turrets. Since Thresh crashed, he set off a chain reaction, and we lost the ranked game. Can anything be done about this? I'm saying Dark Star Thresh cost me the game because Dark Star Thresh is disabled due to some in game problems. So there goes that game.
