I own The Final Shape (Xbox), have completed the campaign, and finished the Encore mission multiple times (normal and Expert). I received Choir of One, but Banshee-44 has never offered the //Choir: Eternal catalyst quest. It is not in the Quest Archive terminal either. My Patterns & Catalysts tab shows Choir of One Catalyst as “not acquired,” but I cannot progress it because the quest never populated. I have replayed Encore, cleared quest slots in case there was some kind of quest cap I could have and done full cache resets. I have done all the side runs as well of the portals near the first section. The plates puzzle's everything. I am sure I had already received the Command frame as I can already select the different options in columns 1 and 2 when reshaping the gun but there is literally nothing else anywhere for me. I dont know what else to do. lf anyone from Bungie is reading this please help me. Please correct the missing quest flag for my account. I have completed the Sample quests before as well. 007 and the like, upgraded Fail-safe. Everything. Im just at a loss now. Please help. Thank you.
