Just wondering, Ezer: Do you know what the uses for Argon, Liquid Oxygen, Liquid Nitrogen and Methane Gas are? Cos I've tried working them out, but no luck at all, and there's literally NO documentation on them anywhere else. Also, is there a way to automate fuel loaders directly with refineries for fueling pads? Cos logic states that there is; put the refinery's output to the loader's input.
