For weeks I've done the raid, done the Preservation mission and each time tried to do the "Melee, melee, interact and shot" for the 3 remaining lore I need for the Ghost shell, but nothing works. Done it with full fire team, done it solo, hit the icons in order out of order backwards, (solo) then same in fire team, quick succession, all at the same time. Nothing works to drop the last 3, worked for 2 of them, and all 5 pillars worked too, but since the door patched to close once in the next room nothing works. Please Bungie fix this as many of us need this for the Gumshoe seal!.
