Returning to my saved game after a long time away. I had cleared out the Troll stronghold with Harrim and Ekundayo in party so I could do their companion quests. I have the option to display completed/hidden quests enabled, and I can see several companion's quests there, including Harrim. But Ekundayo has no quests listed. Do certain quests disappear entirely from the journal? If so, under what conditions?
