Description

Just made rovermax with kerbodyne s3-3600 tank beneath it. This setup moves on any surface over time. At minmus it moves roughtly 1cm/minute to west.
I did confirm this by making KOS module which shows original lat and lng coordinates and compares them to present location.

It seems that this bug is related to planets rotation velocity.

But it shouldn't be like this, there should be some tolerances be made for ships to not this happen.

History

This is because any vessel is actually jumping all the time slightly 1/10th millimeter. This should be the tolerance which should be made.

It seems ship moves to east. not west. Heavier vessels moves lot faster than light. You can see apoapsis ETA jumping when standing still on all vessels.

This isn't landing legs Related, happens without anything attached to bottom of tank. It doesnt happen If tank is root Part, or movement is then very minimal.
