When using the Winch eject function in KSP .235 (haven't tried it in older versions), the head of the winch (and whatever is attached to it) doesn't go anywhere, it just stays stuck where it is. A winch with nothing attached to the head ejects just fine.

It seems like the root of the problem is that when the plug is in "docked" mode, it doesn't want to move relative to the winch base, even if a significant amount of cable has been reeled out. Is this the intended behavior, or a consequence of the new joint system in version .235. I did a quick rebuild of the plugin with the plug set to "undocked" on eject, and that seems to correct the problem, but that may not be the right answer if the "docked" behavior is broken.

Fixed in 0.4.9
