Winning a game and it just "disappears." Unacceptable.

Last evening, while server problems were occurring, I happened to put 45 minutes of my time into winning a 4 v 5, and somehow this match has completely disappeared from my match history. I know this stuff is recoverable. I put a considerable amount of time into that win and I want it fixed. If this happened to others im sure they agree, and riot needs to get their shit together with this. Peace
