I just completed a game of Hearthstone and saw the tickers pop up at the bottom showing quest progress. It did show credit for “Play 3 games as Death Knight, Paladin or Priest 1/3” and “Play 3 games as Paladin, Warlock, or Warrior 1/3”. However, it also showed “Play Naga or Pirates 3/10”. That’s the one that had me scratching my head.
I believe that was a quest I had for Darkmoon Faire’s Frightful Fantasy. While that event is still ongoing, I’ve already obtained all rewards from it and that quest is no longer visible. Probably just a minor display issue unless it has unintended consequences once it’s completed or if it’s not completed by the next such event.
