cloud texture colours inverted after installing + principia apocalypse

[WARD000000]

i'm honestly not entirely sure what's causing this. furthermore principia gave me the following error:

Error extending trajectory for Norihc. Error trying to fit a smooth polynomial to the trajectory. The approximation error jumped from +1.00000000000000002e-03 m to +3.18115758759471634e+06 m at time 2000-01-01T16:40:00,0000000000000000 (TT). The last position is {-1.39243441535804321e+12 m, -6.38638856571567612e+10 m, +6.48828265265136719e+10 m} and the last velocity is {+5.78182088332107469e+02 m s^-1, -2.90273032494905601e+04 m s^-1, +6.65142845207590085e+02 m s^-1}. An apocalypse occurred and two celestials probably collided because your solar system is unstable.

to update: the graphical bug involving the clouds seems to be a main menu only issue, so it isn't the most important bit - the more important issue is norich's orbit colliding with Simetra
