30% discount on selected mastery offers
A few hours ago a message popped up saying "Then end of Season 9 is upon us and you get a 30% discount on selected mastery offers!" from the Dojo. Offer lasts until Sunday. I think there is some sort of glitch with the +1000 mastery offer since every-time I purchased it several of my bird classes would level up. Most of my birds were at mastery level 63.
All my birds now mastery level 70.
