Archivement "Spheres of Influence" Bugged?

I’ve been trying to get the “Glory to the Argus Raider” Archivement but I got stuck with the “Spheres of Influence” because the orbs are not spawning, not before the boss, not during the boss nor after the boss and I’ve tried it a few times already.
Any ideas or something I’m doing wrong?


Ive had the same issue. Ive even had it where the last orb would not spawn.

I had to kill the boss to have the orb spawn, I am also doing this with zero addons running, not sure if that matters

From what I’ve read they made it more difficult to solo so some old guides make not be totally accurate
