QL decrease?

    My steel and plastic are both QL 10 and for some reason my plastic decreased to 1 QL and my steel to 2 QL.
    I produce my own petroleum (10 QL) and iron ore (11 QL). All the research of this products were done months ago.
    I don't remember having bought any of these products. In fact, I over produce them.

    Your QLs didn't decrease.


    They are still at their levels your telling about.
    Therefore you must have bought this products on the marketplace or by accepting an offer.


    Clear your warehouses to get your QL back ;)

    They are normal now. I sold the low quality steel and plastic. And my overproduction replaced the low quality.


    I must have bought low quality steel and plastic before when I though I couldn't produce enough for my product chain. I must have forgotten about it.
    But I waited and waited before I sold theses products in hope they would increase their quality. I think when we mix differet QL, the result is bad quality prevails. I mean, the program must make an average QL, considering quantityXQuality, and rounding to the lower QL. That is why it never increased back to 10 QL.
