[BUG] Book of Mercenaries – Onyxia the Void (6/8) mission instantly ends in a draw

Hello,

This mission is currently unplayable due to a scenario bug.

Issue:
As soon as the battle starts, it instantly ends in a draw — no cards are played, no moves possible.

Steps to reproduce:

  1. Start “Book of Mercenaries – Onyxia the Void” (6/8)
  2. The battle screen appears for 1–2 seconds
  3. Match ends in a draw automatically

Tested on:

  • PC (Windows 10) and Mobile (Android)
  • Multiple devices & networks
  • Different accounts

Troubleshooting already done:

  • Full client reinstall
  • Cache cleared
  • Language change
  • Verify/repair game files
  • Restart chapter from scratch
  • Tried on different devices and internet connections

Result:
100% reproducible. Happens for other players as well (confirmed in this thread).
This is not a local PC problem — it’s a scenario/content bug that needs developer attention.

Video proof:

Please forward this to the Hearthstone development team so it can be fixed.
Until then, players cannot progress past this mission.

This is happening to me, too. Book of Mercenaries, Varden Dawngrasp, challenge 6/8 Onyxia of the Void “Slay the Broodmother,” click Play, two taunt minions appear (game ends too quickly to identify the minions), both heroes explode, match ends in Tie.

Tried it 10 times, same result each time.

To go through the entire Solo Adventure, get to three battles before then end, and then get bugged out so that I cannot finish is not fun. Please look into it.

Hello everyone, I have the same problem. Do anyone have a solution or should we wait for the devs to fix it ?

Même soucis, pas trouvé de solution malgré différentes façon de faire, tentatives de clic sur différents endroits, faire exprimer notre héros en début de combat, relancer une dizaine de fois le combat. Et toujours la même finalité, les deux héros explosent dès le début du combat pour terminer sur une égalité, deck vident des deux côtés.
