## Description of the bug
When someone has their chest open and is wearing armor, their sprite is showing the open ribs on top of the armor. Causes undue confusion about whether someone has their armor and is able to be operated on.

## What's the difference with what should have happened?
Armor should be on top of the open ribs

## How do we reproduce this bug?
1) Open someone's chest
2) Put armor on them

## Attached logs

Reproduce the issue by opening a character's chest and then putting armor on them, confirming that the open ribs render above the armor. Trace the character sprite or overlay handling used by this sequence, then verify that the armor is visibly on top while the chest remains open and operable.
