Not sure where to put this but just completed lore got master and skin lvl 10 so i am sure it is unitentional 
Same thing happened to me
It’s been there for a while.
Shhh, you weren’t supposed to say anything. Now they might fix it! Kappa
Ditto the above. On lore mastery, I got Master of Phoebe but am only character level 9. It’s mostly amusing, but thought I’d say something here.
