Low priority queue from game error

So basically I was in a ranked game a couple minutes ago and for some reason my computer just blacks out. I tried to alt tab, ctrl alt del, alt f4. None worked so I was forced to shut my whole computer off. Therefore it took about 4 minutes to get back on and I came back and we won the game. However once the game is done I see that I lost LP and that I have a low priority queue. I don't think this is fair and I think all of this should be reverted.
