[CLIENT] - Masteries in new champ select glitched.

I viewed a friends masteries after a game. Then upon entering the new champ select my masteries in the dropdown list had taken on the name of his masteries. Furthermore, the numbers indicating which skill tree points were put in had all reset to 0/0/0; however, when going in to edit them they looked completely normal. I did not get to enter the game (dodged) to see what the effects were in-game of this bug. Also, upon entering the next champ select the bug had gone away. I have it recorded in video, if this would help I can upload it and link it in here (too lazy xD). P.S. New champ select is awesome!
