Current known bugs are,
ambush sarcophagus may not trigger properly, making it like the draugr will just stand awkwardly outside.

The ghostly dragon priest may not be ghostly or he may refuse to spawn.

The fast travel option will break troll valley (re-entering troll valley should fix it) (Also this bug is fixed!)

after finishing the bandit questline, Callon does not take the 3 fallholt swords, but they are not marked as a quest item, so you can drop them)
