Leave Buster

While playing a match my video card crashed and had to exit the game only to come back a few moments later. After re-joining my teammates understood and didn't report me, and when the game was over, immediately after it was over a Leave Buster window pops up and puts me in low priority queue FOR NO REASON!!!! We even won that game. I'm so upset about that, and im sure Riot can't do shit about it which is freaking stupid. I know im not gonna get lucky here, but, is there a way to fix this? will you fix Leave Buster? RIOT??
