Clamp-O-Tron Automatic Decoupling

[BazFilmer]

Hi, I've been assembling a space station in orbit of the earth and to my dismay I have discovered that every time I go back the the space center from my station and then return, the shielded coupler on the new part has detached from the core of the Station and is ever so slowly floating away. I am sure that the docks have been coupling properly and I have repeated the procedure numerous times. If it helps when I right click on the Clamp it say Status: locked, but does not give me the option to decouple. I have been playing for a while but have never undergone a long term docking project so the problem might be something stupidly simple. Anyone know whats up?

Thanks in advance,

Baz

Do you have any pictures of the two docking ports?

Status: locked means that the animation on the part is not running.

Is there any chance that some protruding parts of the two vessels are touching, and preventing the docking from being completed? When they touch does the camera jump to the new center of the combined vessel?

Could you try a fuel transfer between tanks on the two separate vessels to see if the game believes they are linked?
