Where are the quests?

I was just wondering, where are the quests like The Rober Baron? I haven’t finished the game, talk to Hans Capon, to completely end the game…to the credits.Not even when I finished the Hans Capon DLC!
Why quests that haven’t been played, during gameplay, or maybe skipped, don’t come up in the end? I don’t think it would break the main story if it did, would it?
Maybe in the next patch?

To start Robber Baron you have to talk to Hans Capon

Have you seen that big warning before entering Vranik? You’ve been warned…
