On my map I see that there are one or two chests still left at the Barnali's Textiles outpost (north-West of king's bridge, north part of souther kyrat). Selecting them shows me that they're somewhere on the second floor of one of the buildings there, but I can't seem to find them. Anyone remember anything about those chests?
Thank you.
EDIT: They don't appear on the first person mini map, but on the large 'M" map.
EDIT2: Same thing at shera's scripture camp, just west of Barnali's Textiles.
EDIT3: I found something similar at Shanah Prooving Grounds, as I picked up some money lying at the place where the chest was marked on the big map, the marker vanished. Same thing at shera's scripture camp. But no money at Barnali's Textiles. So I can't get rid of the markers there.
Best way to find chests is expand the map as far as possible and put a waypoint right on the chest. The waypoint in the actual game world is placed on the chest itself if you placed it properly on the map.
This means you can see it's exact location in the actual game world while getting near it. Often times ones hard to find are underground, or in attics. Some attics are accessible from inside the building via climbing up on objects, others only by going through a hole in the roof via climbing up the outside of the building, or dropping onto the roof via zipline, Buzzer, or parachute.
Underground areas sometimes can be tricky to find. You just have to search the area for cellars, stairways, ladders leading down pits, grapple anchors, or cave openings. Nine times out of ten though, underground chests can be found by finding a nearby ? marking an unknown location, which in the case of underground loot, is usually a cave opening.
