For the Buddy Cop badge, you have to save Detective Hopp in various Dark Astoria story arcs. First in Heather's arc, then later in Dream Doctor's. The problem is that he also appears in a mission from Praetor Duncan, and if I save him there then he doesn't show up in Dream Doctor's mission. If I save him in Heather's mission, but don't get near him in Duncan's, then he appears in Doctor's mission as expected. I did check all corners and wipe out all baddies, but the "???" never appears in the mission objective display if I saved him in Duncan's mission (unless I replay Doctor's arc in Ouros).
Is this intended? Am I not supposed to save him in Duncan's last mission? Madame Bellarose is a similar DA character that can be found in three separate arcs but she doesn't disappear if you find her all three times.
