About a year and a half ago I got super lucky and had the Nechrocasm Catalyst lottery drop. At the same time, I completed the Nechrocasm quest to the point where all I had to do was beat Crota one last time. A couple days ago, I finally got around to pulling the old quest out of the Abandoned Quest Kiosk and beating Crota through a pleasany LFG. The Nechrosasm dropped as expected, but the catalyst is not available to slot into the weapon. The cataylst show as Complete in my collections. The catalyst drop-down in the weapon selection is blank. I have tried to get some kills with the weapon. I have redeemed a Crota Raid triumph that gives Oversoul Essence. I have checked the Abandoned Quest Kiosk. I have checked at the Gunsmith. I checked the Crota Weapon Vendor in a subsequent boss checkpoint completion. I have pulled a fresh copy of Nechrocasm on different characters. I cannot find a way to slot in my completed Nechrochasm Catalyst. Any assistance would be appreciated. Thanks!
