Alpha Client (V6.21, 3159845.3191619.3184109) Mastery Page Bug

Problem: My mastery pages are frozen, as seen in the provided image.

How it happened: I got annoyed at how slow mastery points were being added so I started spam left clicking the masteries, "Natural Talent" and "Oppressor". Resulting in the bugged UI.

Additional Information:

• Regardless of which action I take, only "Sorcery" and "Feast" remain highlighted as if selected, even when I select "Fury" (explained below).
• When I hover over any mastery below Ferocity t4, the icons light up as if they can be selected. When hovered I can also see any masteries tooltip like normal.
• I can still change my masteries but I can only tell if they are changed by looking in the upper right corner of hovered tooltips at the "3/5" or "1/1".
• When selecting masteries below t4, other than "Sorcery" and "Feast", the tooltips let me know how many points are within any hovered mastery.
• Saving a mastery page doesn't seem to have any effect. Selecting a mastery page set up prior to the bug loads the points but doesn't change the bugged UI.
