Mastery Bug

Swapped masteries from my Vi jungler page to my AP Mana Regen page before a ranked match. Didn't take the first time, second, or third time. Fourth time it said "AP Mana" (Title of my page). Double checked before got in the game.

Get in the game? The Vi page sigh

Get to the next lobby it had the AP Mana page selected. As if that was the page that was SUPPOSE to be in the game.
