[MAC][CLIENT] Mac's new client masteries are glitched

In mastery page my masteries are freezed to what I had before the update. I can change them, but the changes are not visually applied. Audio works just like it should. (And as a side note, the client is very laggy in mac.) Computer: MacBook Pro (Retina, 13-inch, Late 2013)

[edit] This mastery bug seems to apply only in champ select.
