What did i do:
I tried to put quality modules into a chemical plant for oil cracking.
What Happened:
It accepted them just fine and boosted the machines quality.
What did i expect to happen:
"Quality modules cannot be used in this recipe" similarly to how "Productivity modules can only be used on intermediate products"
Does it always happen:
As far as i can tell for any recipe with only fluid outputs it'll accept quality modules just fine as long as the machine its in can use quality modules

To reproduce:
Put quality modules into a chem plant set to any recipe with only fluid output. Such as oil cracking

2.0.8 here. Chem plants still offer to stick Quality modules for Lubricant and Sulphuric Acid recipes. Am baffled.
Oil Refinery (and unbottle recipes for barrel'ed liquids in Assembler II-III) don't list Quality modules as acceptable though.

Thanks for the report. This is now fixed for the next release.
