I also noticed a reduction in product sold.
For my fmu corps, usually i would have a turnover of 3.6B-3.9B but it dropped to 2.8B.
So my fmu corps who were making 12-14B a year now make 6.5B a year. @ 200 upgrade.
Nothing can explain this drop. The same amount of product were crafted and there was no change in quality or market price.
Happened about 1-2 weeks ago , never recovered. You could clearly see the drop when it happened.
