Mun lander won't stop moving. Some physics I don't know about or bug?

I'm on the latest PC version. The landing is fine and looks like 5-10 deg slope. Everything is good and still. Then later I go check and it's rocking back and forth. It actually tipped onto the solar panel and I had to use SAS to put it back on it's feet. Then it's good again but later it's moving again. I thought feedback loop oscillation so I've tired SAS on and off, turning wheel authority at 0%, hibernation and doesn't seem to make a difference. Also took off and moved a little distance and no difference. There's no wind so that can't be it. Seismic?

I call it microbouncing. It's an artifact of the colliders in the game engine, and the suspension on the landing legs. Try retracting the landing legs and see if it stops.

You might be able to adjust the tension and spring on the legs also.  Usually, if I'm sliding, I just take back off, head downhill a little (somewhere flatter) and put back down.
