I just got back into Destiny after a while and have been playing a lot lately. I noticed I've been getting some triumphs that have umbral engrams as rewards but for some reason there's a lock icon on each of the engrams. I tried to decode them at the new HELM location but to no avail each vendor said there was nothing for me there including the umbral decoder and the prismatic recaster. I thought it might have been unique to the season pass so I purchased it and still to no avail I cannot use them even after trying to regain quest or doing unfinished story quest. Is there a way I can fix this issue?
