Hello. This bug occured to me when I was standing in house infront of desk. I was standing like nearest to desk I could, I had repeater weapon in hands, pump shotgun on back and I tried switch item in my inventory with weapon in my hands. Before that I loaded repeater in hands with ammunition what I found on desk. Game told me that it cannot remove item from my hands (probably because desk was blocking it) but in moment when I turned back from desk, my character tried remove weapon from hands and weapon get stuck in right hand - when i tried switch that weapon for knife my weapon dissapeared and Knife what I had in inventory and what I tried switch for weapon - appeared in my hands. Problem was, that I coudlnt take anything from ground to inventory anymore - I could only put things out from inventory and my weapon was gone. Only way how I could put something in inventory was with ammunition, when I splited it, it appeared in my inventory. But it ignored empty slots and appeared inside another items (like layered through another items).
