I will make this short and sweet, I had been doing a quest chain for the Pirate lords, at one point they wanted me to hunt down a ghost ship, I learned info about her, turned it in then was told "they would look into her and deal with her later" then did a slaver island quest, after that the pirate guy said he had more work for me......but he didn't, it just stopped. Is this a reputation thing? if it is the game should tell me, I though I needed to progress in the main story, now I am at the point where I need to pick a faction to "do a thing" and this still has not fixed the issue.
