Bug: If you edit the part.cfg file for a mod, KSPMM doesn't delete the part.cfg when you disable the mod. It deletes everything else though, making the part unrecognizable to KSP. If you then replace the mod, (such as when you are updating to a newer version of a mod) KSPMM throws an error instead of replacing the incomplete part folder.

I'm pretty sure the mass of the winch decoupler is the issue. I cfg-edited it to 0.1 (it was 0.0 before) and MechJeb had none of the wobbling and control issues it was having before. It still wasn't perfect, but it was definitely controllable, where it really wasn't before.
