I've reached the Sastasha (hard) duty, via the 'Its definitely pirates' quest. I sign up, play it, complete it, but the quest will not advance. I've tried going via the quest screen, by going to the location on the map and to the duty finder via that, and run through it multiple times. It just won't advance the quest. I've done all the other hard dungeons and they've worked fine. Help
