Crafts keep dissapearing/falling through planets

@AndrewGarrison I appreciate the reply. I believe there is maybe a work around. If I don’t save the location of the lunar base, I just go there on my own (whether it be from Droo or driving from the luna launch area), it seems to be ok with that.

@AndrewGarrison I’m
Not quite sure what that means, but my bases are just crafts sitting on the lunar surface. For example, one base I had consisted of a rover, a large fuel tank, and a small, refuelable lander. They were all separate crafts. When I came back to the location, the crafts were literally falling through the moon. I undid that flight, and tried again, and when I arrived there were just parts lying around.

What do your lunar bases look like? Are you stacking parts on top of each other?
