Seems for me it's just the initial load in. Second load in after game launch fixed issue.

Same problem. Carrying a shotgun on back, magnum as handgun and sks with pu scope in hands. When I load in with the sks in hand w/ pu scope attached, the pu scope is rendered unusable and does the hand view thing. Andy, you may need to have a gun on your back and another withe the scope in your hands when u load in.

Maybe knives and some other weapons should only be able to become badly damaged from opening cans. This way, even if you dull your knife from pristine to badly damaged on a dozen cans, you can still use it as a weapon with lowered damage (once ruined items are actually unusable), thereby more accurately simulating the reality of how a knife is dulled from opening a can and then how useless it would be as a weapon if horribly dull.
