[Client] Rp purchasing screen bugged when champion select starts

Backstory: I opened the rp purchasing thing while waiting for a game. Game was found. Went to internet to surf the interwebz and used command tab to go back to pick my champ. Then this happened. https://postimg.org/image/6cmcrl8q7/ I could not find a button to close it for some reason, so it forced a dodge. After clicked on one of the payment options, it displayed this: https://postimg.org/image/fu0h09ftv/ Still without the exit button, so it forced me to open activity monitor to force-quit league.
