## Description of the bug
Buckled a synth that had lost its head, arms, and legs in a chair and manually placed a gun in its 'hand' slot. The gun then just disappeared from the round entirely.

## What's the difference with what should have happened?
Objects should not just magically vanish when put on another mob.

## How do we reproduce this bug?
1) Have synthetic(might need to be a gibbed synth)
2) Attach synth to a chair so it is standing.
3) Place gun into the synths 'hand'
