We are using the manufacturing module for our coffee roastery. so we have certain green coffee stock and while roasting we use a green coffee as the to consumed material for the roasted coffee (including weight loss while roasting). 

so what I see is that instead of consuming the green coffee, the green coffee is actually being added to the stock instead of reduced. I dont know why, because it says in the Manufacturing order that the green coffee will be consumed.  

I could upload some screenshots if it helps. 

Thanks for your support!
