Vessel Lighting issue, possibly dependant on distance from sun

I first noticed this in orbit around Mercury. Vessels receive light from local light sources and from planet-shine, but not from the sun.

This appears to occur approximately 90Gm and less from the sun, although I couldn't determine the exact distance.

When crossing from a "low altitude" (<85Gm) back to a "higher altitude" (>85Gm), lighting from the sun does not resume, instead the "Ghost Ship" (images 2 and 3) or intermittently, a normal looking mesh with no sun lighting.

This effect persists: after reloading the scenario (current state), after closing and re-opening Orbiter and launching (current state).

The effect is cleared by loading a different scenario.

Can anyone else reproduce this?

Ok, thanks. Will look into it.

The way that the issue persists even on reloading Orbiter, makes me think that there is some variable that has a bad combination of "not initialized by a constructor" and "not freed from memory by a destructor".

But that's a complete guess.
