I wanted to use the body of Assassin_05 for something else, so I pulled off her clothing and found that there is no visible body between her hips and her knees. I know I can remove parts of a body by masking things out, but there are not any masks in her maps. This has happened with a couple other characters as well. One example is when I turned a dwarf into a giant and the boots cut off parts of the leg.
So how is this body masked out without a mask, and is there any way to stop it from doing so?
