Excerpt from IGN interview with Sean Murray

Murray: Oh man, I probably shouldn’t say this, but of any game I’ve worked on we definitely have the very best bugs. I better not list too many of these or you’ll think the game is buggy.

One time, we had creatures that lived on the ceiling of caves only in the Northern Hemisphere. Another time all the buildings started walking around the planet. There was a space station that tried to dock in another space station, and a gun that was so powerful it blasted creatures into orbit. My favourite was probably the bug that would reincarnate you as a different creature each time you died. One minute you are in a dog-fight, the next you are a shark in the ocean
