Wings of Glory FATE boss spinning in Endwalker 6th zone

Date & Time: Always
Frequency: Every time the FATE is active
Monster name: Ahl Ein
Class/Level: Level 89, any class
Party or solo: Both
Area and coordinates: Ultima Thule (X:12.0, Y:35.3)

Steps:
1. Attend the Wings of Glory FATE
2. Regardless of the number of players, with or without an active attempt to draw aggro, the FATE boss spins rapidly, constantly, as if it were retargeting other players. Its target never actually changes, leading us to believe this is a bug.
