[CLIENT] Can't make masteries

I was in champ select for a game and when i tried to change my runes i was not able to do so . I couldn't click to add points on the masteries page, save or create a new page at all. I personally always create a new page for the particular match up im going into per game. So not only was my last page deleted iwasnt able to create another and had to into the game without mastries.
