Widargelt NPC Disappeared

I am currently unable to locate Widargelt NPC in Revenant's Toll. I have completed the quest [The Legend Continues] But it does not show in [Job Quest Log].

The error occurred when I was viewing in middle of the cut scene of the quest [The Legend Continues] where I pressed [Commence] for Duty Roulette.

I have searched for the NPC for past 4 days. I teleported to every location he could be found.

Go back to Erik and check if he doesn't offer the quest again then. If it doesn't appear in the quest journal under completed quests, it's likely not counted as complete.
