Orbit changing with no input
Orbits are constantly changing without any input. Both apo/peri climb/fall after achieving what should be stable, circular orbits.
HD enabled to show redadouts in map mode.
This video shows an example. Vessel in orbit of mun circularized above 80km. Apo/peri changing on their own.
Vessel contains pistons and a kal from breaking ground, and 9 individual probe cores in total.
Save reload doesn’t not fix, but viewing vessel from tracking station shows stable orbit.
Resuming control of vessel initiates the bug again.
I’ve experienced the same with vessels contains no robotics, both at Mun and Kerbin orbit.
This bug makes docking and rendezvous much harder than usual.
