I Need Help
 

Hey guys,
It says to go to Del Fuego and get stuff from 10 storage containers.. but its pointing to the Isla Perdida, and wont let me search anything on Del Fuego I Really Need Help HERE... :(

You likely need to search in the fort at Padres Del Fuego, the crates/barrels.
This is likely the grenade unlock quest.

The game is probably tracking part of your story quest, and thats why it points to perdida.

If you highlight the search task in your Journal and click track, it should track that instead.

Grenade Quest - Flints

you could try disabling the "track" quest option..
It may work..

ill try these guys, thanks!
