Conditions for unlocking Explorer’s of Uldum heroes in duels are bugged, I purchased the solo adventure and unlocked most hero powers and treasures, returned to duels and hero power and treasures are still locked. Fine I do the other objective to unlock Brann’s hero power Dino Tracking (Discover 30 Times…) , I find Brann again. No progress has been made to unlock Dino Tracking or any other progression for other unlocks. Purchasing the solo adventure and completing the second option (Unlock this in Uldum) which works fine in the solo adventure but does not translate to duel’s unlock. Tried multiple relogs and different runs. It seems I’m just locked out of unlocking anything in duels or progressing to unlock even.
2nd but is Woecleaver, doesn’t matter how you obtain the weapon but if you attack with it, it will freeze your game and you must task manager exit hearthstone because if you close it any other way you will forfeit the match. Relogging will clear the bug until you attack again with Woecleaver, then you must rinse and repeat.
3rd Solo Adventure Galakrond’s awakening during one of the battles where you play as Commander Elise, and try to use the exclusive 0-cost spell it will permanently brick that match as it freezes you similar to Woecleaver but even if you relog the bug will still be present and you must concede cause you cannot select any discover card to pass your turn since it is invisible.
