New Champ Select Bug

When you launch the new champ select and change your masteries, your mastery pages fail to update. When in champ select, when trying to select your mastery pages, only your older mastery pages exist. If you happen to delete the older mastery page, the game still shows the mastery page as valid. If you happen to choose the mastery page, you load into the game with no masteries whatsoever.

(Note: This only occurs if you change your mastery pages AFTER you launch the new queue system.)
