I've researched every technology that requires only red & green science, including "Oil Processing", but I can't build Oil Refineries and Chemical Plants, which should have been unlocked with that research. (No other research has been unlocked in my game except the red & red/green ones.) [Using SimpleRecipes v0.0.1]

Here's a link to my saved game: https://drive.google.com/open?id=1TDTLlH_x8ccxjxIL3vgrz5A_NSoMBAJF

Looking at the pictures on this mod page, I see now that assembly machines can be used to make plastic and batteries, and that Oil Refineries & Chemical Plants are not needed in with this mod. In that case, perhaps hide them on the Research Technology screen, since they still show up under "Effects" for the "Oil Processing" technology.

Thanks for this information Dizzie, its really confusing. I will make them hidden, and release a new version... I'm trying to do this without error in game.. Thanks! :)
