I see a space nether in the new Celestial screen and I don't know how one is able to remove it. I see that in the MorePlanets config I can change the ID, but I can't remove it. How do I remove the Space Nether? So far I've updated MorePlanets to 2.2.2 and I deleted the config and let it generate a new one.

Fixed in 2.2.3.
