Currently, advanced oil processing is not required for sulfur processing, meaning it is possible to first get light oil and heavy oil using oil processing with sulfur. Is this intended?
It is intended that you should be able to get light and heavy oil before advanced oil processing, there are many processes in my mods that make use of those oils, and have done for years, before you need advanced oil processing.
Try turning on the new revamp, you get a different set of recipes.
