Hi,
Unfortunately failed the mission in the sunken treasures DLC. I don't even have the diving bell. At one point one of the NPC went to war with me and took the big continent in the sunken treasure map and I got a notification that I failed the questline and it disappeared. I've since taken the island back and the queens' ship is still there. is the quest supposed to restart or is it over and I have to make a new save to do the DLC???
