In map view, if I zoom out past the Kerbin system, all celestial body orbit lines (gray in color) as well as my craft's orbits (several colors) disappear. I just filed this bug today: http://bugs.kerbalspaceprogram.com/issues/5911 They marked it as duplicate, which I get, but the original bug is marked 'low' priority. This is 'critical' for me. I can't play the game past Minmus. Anyways, I was wondering if anybody had seen this before or had any workarounds I might try. To clarify, I just started playing KSP in 1.0.4. This bug is still apparent in 1.0.5. I don't have to do anything to reproduce. It always does this.
