In Reign of Giants (without compatibility with any newer dlc) part of Wagstaff's body is invisible when he is standing. The part reappears while he is walking or doing other animations, but still disappears while he's standing.
Steps to Reproduce
Create a ROG world with Wagstaff (no compatibility with other dlcs), part of his body will be invisible
