I can't get Lost Lament.
I finished the part where you complete. Bunker E15. Then, I saw my friend was doing the final step that I needed to do next so I joined him. Upon completion, I spoke to Banshee and he said what he was supposed to say but I didn't get a sword. I still had broken blade in my inventory and the quest was gone. I could not find any way of fixing it so I dismantled the broken blade. Now I can't get the quest or the blade back
Bungie pls fix
