Dragonfly scales duplication with scaled flooring [1=6]

Hello, I found a glitch yesterday.
I'm not sure you know its existence because I think that it must be absolutely fixed. There is huge ...

Here's the problem:

- Craft Scaled flooring with > 1 < scales
* You get > 6 < scaled flooring

- Craft the deconstruction staff

- Use the deconstruction staff one time or more on your scaled flooring
* You get > 6 < scales ! ! !

I think it should simply not be possible to uncraft the scalled floring unless they stack by 6.
