I'm having a really frustrating issue where when I extract the files into the game data directory only some of the parts are available and they're all completely nonfunctional. I only have the orbital mini launchpad thing, containers for the resources, and the metal furnace, and none of them do anything. When I check the parts folder there are many other parts but only the parts I mentioned appear and the EL test craft doesn't work because it uses parts that aren't functioning properly.
