I totally confirm this inconsistency: never encountered the artist in act 3 I could refer to him on the first dialogue with the MC. I decided to talk about the other quest (the thrumbo one because i met him earlier) and went for it. When back I could never talk about the artist again (I still haven't found the artist at this point) even if i unofficially know that the quest reward is about him. So at this point i'm afraid to make progress in the thrumbo quest, i'll come back when i meet the artist.
