Crown of sorrow bug (specifically for flawless)

So i wanted to go for flawless a few days ago and found it it was bugged. I find it frustrating there has been no response from bungie on this so i am making this post to maybe get some attention to the problem.

( If you dont know the bug at the 4th encounter without wiping before it the crystals bug out and wont respawn making the fight alot harder (not impossible i know) now i wouldnt personally mind the challenge but deu to it being a bug its hard to find a group for it now since everyone is waiting for it to be fixed but honestly i dont know if bungie knows )

Edit : Update on the bug from dmg
