Phantom Game

I was literally just 20 minutes deep in a Xerath game, then i got the "attempting to reconnect". i thought oh thats fine, ill just exit and reopen the client and come back in. Nope. I relogged and when i logged in, i wasnt welcomed with the "reconnect" button. I was put in the screen like i had just logged in for the first time. I dc'd, tried to reconnect, and the game acted like i was never in the game in the first place? The game isnt even in my match history.
