Was unable to get Essence of Death on main character for the Witches Festival holiday event. Wasted a lot of time trying to fix it but couldn't. Probably an active quest or quest item bug.
Solution: Was able to complete it using a different character and doing a common delve in zone that character hadn't done.
I tried to collect one in a public group dungeon and it wouldn't work. Went to a simple delve, killed the boss once and there I had it. Maybe just try a simple delve.

So far I have tried a public delve, a group dungeon.... and I had thought a regular delve.. maybe I didn't do the regular delve. Thanks for the suggestion though, I will try that one tonight.
Two years later this bug is still an issue. I've killed multiple delve bosses multiple times in Summerset (IE: I've killed the spider daedra boss twice and the den mother twice. Also tried dropping the quest and picking it up again.)
Waiting for the bosses to respawn for no reward is absolutely awful.
