RVE/Scatterer and RSS at 160km?

I know it's not been updated past 1.0.x, but I installed the old RVE for linux 64bit mod, along with its other stuff.

I see people playing RSS with great visuals. I have them too... mostly.

Between 155km and 165km, the clouds basically disappear, and Earth is clouded in a foggy vapor shroud. Not a big issue, but that is kind of an ideal LEO for a lot of early contract missions.

Again, it's not a big deal, but has anyone else seen this?
