There is a visual bug where a gun renders another guns' weapon attatchments (pistol and main for example) and puts them sideways. This happens after using up a grenade slot, so I think it might be some accidental indexing bug due to bad indices after removal of a piece of gear.

It does right now resolve itself after a few weapon swaps, I think usually because it hits some index-out-of-bounds and quietly corrects itself back to normal.
