It might be bugged then. It's not for everyone since I've started a playthrough on this version of the game and it triggered without an issue. That just means it's not easy to identify what the bug is. FWIW, I was doing this on a New Game +
How far have you advanced on the main plot? Have you finished off Draknar? Or reached Winterfall? Have you done the Reverse Summoning Ritual?
EDIT: Also, another fairly obvious thing that I overlooked is that Cult Leader James should be dead, so that's a reason it might not be triggering.
