New Tattoo Quests

[KATIE4149]

Okay so I searched for this everywhere, and didn't find anything so sorry if this has been questioned once before!

Anyways, so I've started the new tattoo quests, and the first one I've done fine with up until about 87% when it asked "Find a document in a storage container" it tells me Fort Dundee, which I thought was the fort in Padres, but every single one told me "No quest items found," after searching. Every other fort said, "Nothing interesting." Gah, its confusing.
The second tattoo quest told me to kill certain enemies on islands, like for ex. skeletons on cutthroat, dread scorpions on outcast, giant crabs on tormenta..etc. When I got to the giant crabs I killed about 10 of them and none of them registered, it didn't even say "Crab claw not found" like it normally does for quest stuff.

What am I doing wrong? Help!

Thanks in advance!
