So I killed Taniks in the story mission, where I should have received the essence of isolation to make the dream and gauntlets. But he didn't give me the essence. I went back to the lectern to see if I had dismantled it or something. I can't buy the essence because I can only hold one at a time. I looked in my quests tab for the essence but it wasn't there. Is there any way to fix this and has anyone else had a similar issue?
