Hello, playing on PS4, playing in hardcore mode but I don’t think it makes a difference.
I started the quest robber baron earlier in my playthrough and almost finished it. I actually did the pacifist way when I convinced Wolfin to go away, leave the loot and some groschen, and reported it to Bernard.
The only step I was missing is to report back to Hanush to finish the quest but I didn’t.
Instead I kept going on with the main quest until I went to Vranik, from there the quest cancelled but I didn’t care and kept going. After I started the Siege quest, I remarked Bernard’s optional quest marker was in the forest east of Talmberg, I joined him and saw him walk on foot in the forest, and Capon was also following him a couple meters away. After a while I saw they were going back to the forest encampment, where they were waiting for me during the Robber Baron quest.
After this, everytime the main quest needed them, they would teleport back but as soon as it’s over, they just go back to the encampment again. Even during the epilogue, as soon as you arrive at the end of the road after Neuhof, Capon goes back as soon as he goes off his horse.
I checked Wolfin’s camp, the bandits are all gone and the camp too.
