Quest bug – Atlas bosses killed but not counted / Arbitrator fragments lost

Hello,

I'm writing to report a quest progression bug in the Atlas endgame.

I killed three Atlas bosses, including the Arbitrator of Ash. I received the loot drops from them, but the quest was not marked as completed. Despite this, my Atlas maps have progressed further (the next areas are now unlocked).

The main issue is that because the kill wasn't registered for the quest, I can no longer obtain the free Arbitrator fragments (or the guaranteed first set of keys) that should be awarded for completing this quest step. Since the Atlas thinks I haven't killed them, but the game state has moved on, I am now locked out of earning those fragments through the intended free quest path.

Could you please manually complete this quest for my character or reset the state so I can receive the quest rewards?
