Left 4 Dead 2 Nunchuck Jigglebone

Hi, I’m trying to replace the tonfa in Left 4 Dead 2 with Michelangelo’s (TMNT) nunchuk, but I’m having no luck with getting it to work. The world model looks OK when someone isn’t holding it but when someone holds it, the chain and other stick of the other nunchuk appear between their legs.

As for the view model the same thing happens. The chain and the other stick aren’t visible, they are only visible when you set the fov to 150 where they float above the survivors head.

This is driving me mad, does anybody know what the problem might be and how I would go about fixing it?
