1. BTS' "Blue and Grey" is a track on BE album, and not a single released only for Halloween. The fact that it's part of the album yet you can only play it only "Halloween Special" themed cards ans not the BE album themed cards, is really ridiculous. Why not allow players to play it using BE album themed card instead? Why exclude them? 2. I appreciate the team efforts to add Seventeen in the game. But, the bugs are really bugging me, they keep freeze the game.
