At first, I got a message saying:
9: Not Use
So, I talk to her again, and got the "this is far from over", then I got my doll.
If you can't get your doll, I'd try sending in a bug report to them.
If you're not sure if you got the doll, open up your weapons tab (the "I" button), and look at your doll slot, if it says "Pirate Doll", you got the newest voodoo doll.
Hope that helps for all
