Hello all,

I have a huge problem: Nitrogen Monoxide does not show in my receipes....so I cant make the acid with it. That means I can not really mine Rubyt ore.

I serached this forum and found a bugfix for Nitrogen Monoxide not giving back the metal frame. But this bugfix did not help me.


Any help maybe? Thanks in advance



little EDIT: I reset my teachtree in singleplayer mode (we play on a server) and rsearched everything. it showed up then. but that cant be the right solution. we dont want to cheat us the whole teach tree. we dont play marathon for nothing

I also noticed mud is missing. I can't make mud at all or figure out how to get mud.

Did you update to the latest versions of refining and petrochem?
