Hello, I wanted to ask, if I can reduce the cost of my rockets by editing some files. Yeah I basically wanna cheat, because I´m building big rockets that exceed 4 million rocket-parts and I don´t want to refule my station with ore every hour for I don´t know how long. (fyi I also use Keridian dyanmics, but I think that just adds some fueltanks and better looking equipment)

Does RSS and RSSVE work with Kopernicus? Because I get an error message when I´m done loading KSP: "Kopernicus was not able to load the custom planetary system due to an exception in the loading process."
