That's not the quest, that's the minigame.I had the same problem. I freed the pearl and went to talk to jack but nothing. Although, I see the bp quest is still in lookout, so I think I can try again. I just am not motivated to try again because it didn't work the first time.
Can they actually “see” what was done/accomplished or, did they just give out a code (to provide a workaround for you) taking your word that it was finished?The black pearl is a long quest so I wouldn't want them to have to do it over. But support can see that they did it so I wouldn't have any problem with them giving it to people who did the quest. They did that for me on a pirate where I didn't get the raven's cove teleportation totem. I did the quest but didn't get it and they gave that to me through a code.
