Thank you, Taniwha. And for everyone else as well. Everything seems to be working here, and maybe it was already working when I posted my latest one up above. As a side note: Maybe I am just dumb have a big stupidity bar, or things have changed and I'm not crazy here. If the first one is the case, please apologise my stupidity. If my weak (WEAK!) memory is correct, we used to have four buttons on the converters: Jet Fuel, Oxidizer, Rocket Fuel and Monopropellant. Now everything I see are the first two ones (jet fuel and oxidizer) on the medium converter, and the last two ones (rocket fuel and monopropellant) on the heavy converter. Now, I spent some good ammount of science in a depth research which showed me that "Liquid fuel (is), sometimes called jet fuel". Then, I can assume those are the same and don't need different buttons for the same stuff. But what about the oxidizer and monopropellants? So, if I'm correct, only Medium Converters are capable of converting Kethane into Oxidizer, while only Heavy Converters are capable of converting Kethane into Monopropellants? Or is there really a bug? I couldn't find anything on the items description or at the Kethane Wiki that told me this. If there is some info proving the contrary and I didn't see it, please, rub my nose into it. P.S.: I'm expecting a 5-word answer.
