Says I'm 'in-game' after game is over

I played a game, and when I finished the league client froze. When I attempted to log into my account again, it automatically loaded me into a game (white screen), but it is a game that is already over for a while now. What can i do? I've been waiting for it to go away, but it hasn't. Whenever I connect, it starts a new game with no one, only a white screen. Also, on another note, I was in promos to s5. I lost the first 2 promos due to buggy client, bugsplat during champ select which made me dodge... even after I did a full repair :(
