I found a bug with Fonso:
I built a small test craft to explore Sarvin's moons, and I attempted to land on Fonso, on the flat plains. When I reached an altitude(I don't remember the specific altitude), it appeared that I descended into an invisible layer of the surface a little bit above the actual surface, then every thing went black. Fonso, the skybox, everything disapeared. The rendering returned to normal when I ascended back up.
I didn't test the mountain peaks to see if the bug only works at a certain altitude, or at a constant height relative to the surface anywhere. But the glitch happened below the altitude of the nearby mountain peaks.
I knew I took screenshots but for some reason they didn't save.
Thanks for any help
