Party Quest - Lord Pirate

Well I’m not a fan of PPQ really but since this new quest was added I thought I might as well do it. So in the last week I have done the 350 PQ's and got the Lv 90 Hat. You can see that in the screen shot below.

 Spoiler

So I have acquired all hats yet the quest is still in the In Progress section. Does anyone know how to move it into the Complete section? I thought the goal of the quest was to get all the hats?

You have to get out of the PQ range.
