It's possible to accept the next quest in the quest chain after this one, without ever picking this one up. I'm running Wholly + Grail + Quest Completionist addons, which does show the quest marker on my map as something I can pick up, but Captain Drine doesn't ever have it available. When I run the following script: /run print(C_QuestLog.IsQuestFlaggedCompleted(71179)) to see if I completed this quest already, it returns false. However, the quest named Primal List, which is the very last quest in this quest chain; when I run the script for that one to see if I have completed it, it returns true -- meaning, I completed this entire quest chain without ever doing Look to the Overlook.
If you fall into the same boat as I have, then run this script to see if the last quest in the chain shows complete for you (there's a chance that it might be complete): /run print(C_QuestLog.IsQuestFlaggedCompleted(66472))
