How do I start on this planet? I can start the scenario and add these mods in from the load game screen, or I can do a custom game start, guess at all the settings and add all the mods, but the planet doesn't show up?

With the help of some googling I managed to spawn the planet in, and I even managed to teleport my engineer over to it, but then I still don't have the rover.

After spawning the planet it also still isn't an option to start on if I attempt a respawn.

How is this supposed to work???
