I made a video to describe the issue:
I'm struggling with an issue already for a while: when a new craft docks to my space station, other attached/docked crafts undock straight after. Some excessive force is suddenly applied, forcing other crafts to undock. I've tried to power off the other command pods as well and I dock without automatic targetting set. FYI: engines are idle, RCS is doing nothing when docking.
This seems a bit like a bug to me. Is this something known, or am I doing something wrong here?
