problem: How do i get grenades?

[erazor]

I just hit lvl 20 and got the quest for grenades unlock and went to jack sparrow. After talking to him, he said something about going to the Port Royal Docks to pick up his weeks supply and get some of my own.

But then the grenade unlock quest disappers from the quests list and id on't know where to go / who to talk to.

So i went to port royal and tried to talk to every guy around the docks.. no luck.


What am i supposed to do?

Thanks for any help!
