"Celestial bodies cast self shadows."

[Motokid600]

Im not sure where to ask to solve this, but I figure id try here. I have this circular shadow cast onto the surface of the Mun. It seems to be draw distance of sorts for the ""Celestial bodies cast self shadows." ( will call this CBCSS ) feature. It grows and shrinks based on zoom. Not been elsewhere to see if its a non-atmospheric thing. I believe it is related to the "CBCSS" option in graphics settings. I would prefer to leave it on as it does look better especially with parallax. Within the draw distance of that circular range the shadows look amazing. Im using the full suite of visual mods except for TUFX. I was wondering if maybe an Astronomer Visual Pack issue so if need be ill ask there. Or even Parallax? Not sure where to start.

Edit: It does indeed go away with CBCSS disabled.

Edit2: More pictures.
