Stats screen shows match of spectated game and not the one I just finished playing.

The stats screen showed the details of a game I started spectating earlier and not the one I just finished playing.

Steps involved:

1. Spectate a custom game of URF mode.
2. Watch champion select and then wait for the delay before the match begins.
3. Watch a few minutes of the game. I didn't click on anything until I wanted to stop watching.
4. Open menu to quit the match and exit.
5. Start a matchmaker game of URF mode.
6. Finish playing URF mode game.
7. Notice that the stats are of the game I spectated earlier and not of the one I just played.

Maybe it's just an URF mode thing? Hope it helps!
