Thank you for advancing my ticket!! :) I'm about 2/3 done with the ring station. I will add a control to start and stop rotation.

I just uploaded the SMENT here. If you can't access the SMENT let me know and I will find a public server to spawn it on.

I have been experimenting with this issue, and I think it has to do with distance - though I'm not sure if it's measuring distance from the core or the docking module. If I align to the rotating core, I will stay aligned and rotate with the core until I reach a distance of about 50m, then I get a "gravity neutralized" message and alignment ceases. 50m is a short distance to work with if you are designing a rotating ring on a space station. I hope this threshold increases - or is measured in the future from the surface of the object, not the core.
