Bug Fixes and Game Improvements

  • [Hearthstone] Fixed a bug where the new Omen Demon Hunter Hero Skin’s Hero Power could not be upgraded through effects like Baku the Mooneater.
  • [Hearthstone] Fixed a bug where Sunfury Clergy unintentionally gained Rush.
  • [Battlegrounds] Fixed a bug where Discover effects could sometimes Discover non-Battlegrounds cards.
  • [Battlegrounds] Fixed a bug where Sinrunner Blanchy could gain infinite Reborn under certain circumstances.
  • [Battlegrounds] Fixed a bug where Putricide’s Creation could be tripled under certain circumstances. The triples were failed experiments that lost some of their combined powers; it’s better these Creations remain unable to be tripled.
  • [Battlegrounds] Fixed a bug where a Corpse Refiner made golden by Greta Gold-Gun would not sell for the right amount of Gold.
  • [Battlegrounds] Fixed a bug where a minion that received Reborn from Baltharak (one of the tokens generated by Mecha-Jaraxxus) would lose Reborn if tripled.
  • [Duels] Fixed a bug where the Hematology Hero Power always assumed the player had 3 unspent Corpses if the player had any.
  • [Duels] Fixed a bug where the Hematology Hero Power could hit 0-Cost cards in your hand.
  • [Solo Content] Fixed a bug where a card adjustment to Forsaken Lieutenant made one of the Book of Mercenaries encounters impossible to complete.
