I was running around Stary and found a jacket, it had items on all 4 slots, I wasn't able to pick it up, neither the jacket, nor the items within it. So I figured: "This might have been looted by somebody else, and this is the items inside his inventory right now."
Since they were all stackables (Ammo and rags), I was able to split them up, bringing them to my inventory. He had about 36 rounds of 308, one of the stacks were showing up as Shotgun Bucks and kept like that until I splitted it up. And the Rags.
I also seen a lot of items around that were showing up as pristine but were actually damaged after you picked them up.
