Docking Port Sr.s not docking

[djshaw]

Hi everyone!

I am dissassembling and reassembing a space station using the eva construction mode. I've removed a Docking Port Sr. to get access to some reaction wheels underneath, to put the Docking Port Sr. back on. After reattaching the Docking Port Sr., it never attaches to any other docking port. (I'm using MechJeb to help--if I put the docking port on backwards, MechJeb sets up backwards, so I'm certain I didn't attach the docking port backwards). I thought the issue was because I had an Engineer on a ladder and that docking wouldn't happen if there was a kerbal on a ladder. However, after stowing the kerbal in Science Lab, the issue still occurs.

Both vessels that I'm trying to dock have electric charge, and other resources (monopropellant, oxidizer, and fuel), and both vessels have communication links to KSC.

Any suggestions on what I could do to resolve the issue (other than sending new reaction wheels from Kerbin)?

Thanks!

Question moved to modded support. Do you have screenshots of the ships as you are attempting to dock?

The docking port may be stuck in a state where it thinks it’s already docked to something, it’s a fairly simple fix but requires a bit of save file editing to do so and I can’t remember exactly what needs to be changed, or what to change it to. Try a different docking port, or replace it with a new one instead?
