I have been left from this game for 4 years. And recently I downloaded the game, installed mods including RO, and then I found the engines and RCSs using normal temperature fuel such as MMH+NTO are unavailable. The game version is KSP12.2.3, and I install the mods from CKAN.I found the cfgs in RO define Helium as engine fuel. That's unreasonble. Could anyone tell me how to solve it? I also want the flattable heat shield avialable in RO environment, but RO define almost all parts' max temperature at 1073K in a way I don't know. If someone kindly tell me how can I get that?
