Hexxat's and Dorn's ToB quests not starting

I have finished both Neera's and Rasaad's quests and have almost made it to the end of the game, without Dorn's quest starting. Can this be fixed with a console command or anything else? I have also started Hexxat's quest in Amkathran but I can't travel to the quest location (Force talking her doesn't work).

Any help would be appreciated. I have had problems with the new quests in SoA as well. It's really a shame since I really enjoy the new locations.
