I have noticed the blue lockers in guard houses will sometimes spawn items/loot. If you look at the shelf you can see a magazine of ammo but there is no menu prompt to pick up the item. Also if you go into inventory in does not show in the general vicinity either as nearby for pickup. I have tried moving around and jumping yet the item can not be picked up. This has happened whenever I am in a guard house and if an item spawned in the locker.
