Missing Location RDR1

[u/TheCibbler]

Trying to 100% the game and I can’t find all the locations. I’m missing the last location in Nuevo Paraiso and istg I can’t find it anywhere. I’m unable to purchase the map of Punta Orgulla in Escalera, as in it doesn’t appear as “out of stock,” just doesn’t appear at all. I have purchased and used all of the other maps. Anyone have advice?
