Reef Boss - Nassar: Immune to damage, does not phase.

This is the second time I have attempted to get Atlas progress for Reef map, and the second time the boss has bugged out and never drops their immunity shield. Have to abandon map.

Bug report: 3.241.947,550

same

same, i use specters/cold damage, boss doesn't phase, tried multiple maps. Freezes on different phases every time

Same for me, very annoying. Using cold damage with minions. Stuck in the immune phase. Asked a friend to join but he couldnt kill him either.

GGG need to address this.

Edit: I tried again and it is the unfinished Syndicate mission that makes the boss bug out.

Edit2: I went in again to get the Pantheon and used divine vessel. He bugs out again. This time at 50%...

Edit3: A friend killed him for me. But GGG needs to address this issue for people that dont have friends.
