Client bug

I just played a game of ranked and after we won the client just went away and when I tried to open it, it said there was already a client running. I opened up task manager and there was no client running... So I opened lol and it said I hadn't played that game that I just won! game ended around 3:58 CST I was jax and my teammates were teemo, malz, mf, and ivern vs a rengo, olaf, anivia, zil, and cait. I hope you can get my game back please. Also try to fix that bug too please!
