When I open SE+K2+Thoriated filament+Rocket-Silo Construction+Schall Uranium Processing mods, the last step is to build the rocket silo, I need to provide the rocket controller, and the rocket controller needs a CRT, and the CRT needs an electron gun, and the electron gun needs a Thoriated filament, and the Thoriated filament needs a uranium 238, and the uranium 238 needs a centrifuge, Centrifuges require rocket silos to launch satellites and create rocket tech cards to unlock them, creating an endless loop
