The Duels Signature Treasures that require 15 Scholomancer Academy unique epic cards are locked, even though I have all epic cards for that expansion. It says I have 11 epic cards out of 15.
When I first saw that warning, i went to my collection and crafted 3 or 4 epic cards which were the ones I didn’t have any copies. I checked the treasures again, but it still says 11/15. Now when I count my unique epic cards, I have 23 of them. I have more than enough.
I’ve spent 1200-1600 dust to craft those cards. I didn’t really want to have them, I just wanted to unlock the treasures. It turns out I didn’t even need them in the first place. I crafted them because of that bug. I want a compensation, arcane dust or something.
