I post this again to explain it a bit better to any developer who might be reading this.
Mouse/keyboard? Controller? This does not affect to game or leads toward the bug
Steam? Xbox? Xbox
What were you doing leading up to this bug? Saving the game
Any steps that we can take to reproduce the bug on our end is appreciated. Just go into your habitat and save the game. I always went into my habitat and went back out of it before i clicked on "quit to main menu". A new screen should show up now and at the bottom a circle that spins around. That circle, which means it is saving, freezes after a couple secondes and unfreezes after maybe 10 ish secondes. After this it spins again and brings you to the main menu. You should close the game because thats what i did. Launch the game again and launch your character (i tried using the same character i used before but even that did not work) and it should bring you to a newly generated planet.
