AC4, Buried Treasure Map Issue
So I've finished the main story, and decided to go for the collectibles and get 100% synchronization. However, I have run into some issues trying to get the buried treasure chests. One specifically.
I've gotten all collectibles (to include treasure maps on bodies and from taverns). I've also done Kenway's Fleet and done The Empty Cellar, Scarlatina, and Great Reputation 1. However, either I've done Great Reputation 2 and it's gone now, or it has not shown up for me at all. I have done Great Reputation 3, so I would assume that I had done Great Reputation 2.

Unless, I'm missing something and it is just too obvious me.
Any help would be appreciated.
