Describe the issue

Amputated arms, whether amputated in-round or via the setup menu, do not properly disappear when viewed from the side-profile.

Strictly speaking this is a duplicate issue of #12353, but that issue is three years old and I've done some extra testing:

• This does happen with the left arm.
• This does happen if the amputation was mid-round.
• This does not happen with legs (but if only one is missing, it'll look like it's still there because the other leg will be visible. If both are missing, they disappear correctly.)
  
• I don't think this is just a Martian thing, but.........

How to reproduce

1. Have a horrifically traumatic event where a greimorian infestation goes untreated and blows your arm off (or just use the character setup window idk)
2. Still have an arm from a certain point of view.
