I've got an issue with the Python client where vessel.control.legs only works on parts added in odd symmetries (1,3). Legs added in even symmetries (2, 4, 6) are not controlled.

I tested it with nearly-stock (only ModuleManager and kRPC installed). See attached craft and python files.

Is there any more debug info I could provide? Does anyone else see this problem, too?

Could this be related to #261? I noticed that iterating slowly over vessel.parts.legs (allowing enough time to completely retract a leg) would eventually retract all legs, but if I set the deployed attribute of another leg of the same symmetry set to False while the legs are still in motion, the set will actually extend again.

Yes it's related to #261
In This File , line 170

public bool Legs {
            get { return parts.Legs.All (part => part.Deployed); }
            set {
                foreach (var part in parts.Legs)
                    if (part.Deployable)
                        part.Deployed = value;
            }
}

Since every leg is deployed once, and every deploying call deployes all, even nubers will do nothing in the end. Stumbled across the same Issue while building external KSP hardware.
