[2018] How do you start forgotten sanctum???

DLC is installed, had one event trigger with a wave, got the missive for the pet thing at the petris overlook,but been sailing around the Deadfire for an hour staraight and nothing else, no missive, scripted event, or quest update. Went to the black isles only thing there is hall of unseen dungeon I completed in base game

Hey nyhrdcore, I'm sorry this is not working as intended. Would you mind sending us one of your save files by emailing [email protected]?

In the meantime, you may be able to advance to the DLC by just going to the center of the unseen dungeon, there is a new staircse in the center that leads to the DLC.
