Switching crafts causes all lights to vanish (modded)

[skygunner58203]

So, I have an odd question.  I've modded my install, and while it does take a while to load, the only errors I get deal with part modules somehow doing double duty.  HOWEVER!  If I launch a craft, its flight and textures are fine.  I can dock the craft to another one, and its still fine.  The issue arises when I switch between craft mid-flight.  It doesn't matter if I dock first or not.  If I hit the hotkey to switch to a nearby craft, it switches.  But then the world turns black, the skybox and sun vanishes.  Its repeatable, both with new saves and old saves.  I'm thinking a mod I installed is causing issues, But I have no clue which one.  I've had larger mod installs than now with no issues.  Should I just re-install KSP and add mods slowly?  Or see if I can catch an error in the log first?
