When coming across [clothing_upper] PATROL JACKET and selecting to equip it [XO_controller_(Y)] from the ground, the item is equipped; however the previously equipped [clothing_upper] Jacket / Top disappears.
This has happened multiple times and is consistent with [land_mil_tent_big1_2] MILITARY TENT & [land_workshop1] INDUSTRIAL WORKSHOP.
This does frequently happen with other items that do not appear in vicinity search but can be seen and retrieved manually from the ground / surface.
I believe the mentioned issue with [clothing_upper] PATROL JACKET is specific to clipping through the tent floor and not being able to be retrieved manually.
