The Beholder Hive at the Barren Wastes has a couple of related issues in need of resolving:
- Only one person gets the 'PING!' when activating the quests. (Everyone else gets a BLANK JOURNAL plot_beholder update in their unfinished journal record - they CAN enter the hive)
- When the 'boss' is defeated, there's no 'PING!' / quest update. (Person who activated the quest killed the boss)
- As a result, it's not possible to end the quest. The only options are to abandon or to continue.
