## Description of the bug
While removing some upgraded plasteel cades (e.g. acid proofed cades) to change what upgrade they had, i realised i was getting 8 plasteel sheets back instead of 6 plasteel sheets 2 metal sheets. I don't think it is suppose to be this way, it would be a slow but effective way of converting metal sheets into plasteel sheets.

## What's the difference with what should have happened?
I expected to get 6 plasteel sheets and 2 metal sheets, plus barbed wire if applied, from deconstructing a upgraded plasteel cade. Instead i got 8 plasteel sheets back, and barbed wire if applied, but no metal sheets.

## How do we reproduce this bug?
1) Keep an eye on your plasteel sheet count.
2) Build a normal, non-folding, plasteel cade.
3) Upgrade it using 2 metal sheets, any upgrade works for this bug.
4) Deconstruct the upgraded plasteel cade, by using a Screwdriver Wrench Crowbar.
5) Collect the plasteel sheets from the deconstruction which should land you with 8 plasteel sheets, and no metal sheets, from something that costed 6 plasteel sheets 2 metal sheets to build.
