I had this, loading a previous save just before the crowning did the trick.
I approached lunden from the water. This resulted in the fact that the story arc didn't activate I think. Few characters on the streets, they talk gibberish, and side quests won't initiate. When I reloaded a previous save, and approached lunden from the north, the bug was fixed. Waste of my time though, I finished everything apart from the side quests.
