10-17-20 edit: This bug is fixed, and the quest can be completed, allowing progression toward related achievements.
The Doomstone quest is blocked
- In Thousand Needles, The Twilight Withering, get The Doomstone quest from Magatha Grimtotem
- Activate the Elemental Nullifier near the targeted Animus
- Attempt to fight Animus
The Elemental Nullifier does not trigger the quest encounter. Using the Nullifier briefly flashes the Elemental Nullifier power bar before disappearing. Animus appears to have a shadow FX applied before disappearing, and Animus returns to a non-combat state.
Notes: Bug seen in version 9.0.1 (36021) on 9-25-20, and reported in-game.
Attempted with a Horde character.
Restarting the client does not allow quest completion.
Abandoning and requiring the quest does not allow quest completion.
