In v 1.6.10, when traveling to the earth, I end up somewhere with a starry background, no ground, and I am in a constant state of using the parachute. The ground seems moon colored and there is one single star tile square on the floor, however I can not touch the floor, I am hovering. I cant move anywhere or do anything. The only way to get back to the moon is to restart the game.

The overworld is disabled, you are not supposed to go there.
