Need help with this Custom Planet

I've tweaked with a few of the vanilla planets before but this is my first attempt at something completely different.

The playfeild loads fine but as soon as I entire orbit or try to teleport inside the planet the game throws a "null" at me and the planet disappears completely and I get CoQ.

If anyone can fix it your very welcome to use it anyway you wish.

(Rename to Playfield.yaml to test)
