I don't know how to make nitrobenzene so please let me know!
Note: I use google translate

There totally is a recipe for it in the mod files, but I investigate this bug for quite some time now. Somehow this recipe is not loaded correctly and it works in some save games and in some it does not. Sadly none of the mod maintainers answered me in the last few days.

I got an answer, but the issue seems to be quite the mystery.

this isnt a pyhightech issue. stop cramming overhauls together and expecting things to work.
