There was another patch later on the same night. I have not patched, as I know better:
Hotfix Notes: December 10, 2024
*** Quests & Events ***
- Year of Darkpaw collection achievements should now always be visible.*
- The Everyone in the Pool achievement in the Brood Architect Hazuri mission can now be completed.
- In the Brood Architect Hazuri mission, Hazuri no longer teleports to break open eggs. This should prevent issues with him teleporting outside his tethered area.
- The EverQuest Team
*Note: You may need to patch your client before this update appears. It can also take a few minutes if your achievement data has been cached.
