Just a small issue but there is a chest you can't open on the Moon, I come across it 2 times now. It spawns but the "X to collect" prompt is missing (and hold x does nothing). It located in Archer's Line inside lefthand outbuilding by the main building under the mag rail (see attached pic). If you enter the building on the left hand side (nearest the patrol spawn) and turn right the chest spawns on top of the rack in the corner. Don't know if anyone else has come across any other chests like this but feel free to add them to this thread.
