Bug MultiPosition Constraint and Bones!

- Unity 2020.3.5f1, Last Animation Rigging Versions.
- Bug when attach some Bone or some object inner some bone, at Source, from MultiPosition Constraint.

The Expected was that the movement of my RIG was linked to the movement of the object that is inside a bone, but this does not occur. My RIG Movement is totally crazy.

I am trying the RIG that controls the right mother, to assume the same position as the same left. Or vice versa. However I found that I cannot do this due to this reported problem.

To get around the problem I have a simple component to an object that simply follows the hand I desire. And so I can make my RIG use it as a reference and not the hand ...

The problem with this is that I will have more things like that, and therefore I will have a lot of components using the looping Update for something really silly.
