Its not a host parameter because I host MP games with friends and it still occurs, the only way to change these types of clothing items is too loot them off either dead BLUFOR, OPFOR or civilians. This glitch also creates big mess piles around supply crates in MP games because people constantly try to put the clothing item on.
This would also categorise under Inventory issue, but I put categorised it into MP because it does not occur in SP.
