Can somebody look at the following images and tell me based off of the hierarchy and constraints why the indicated controls don't follow the joint chain and parent objects once I bind the skin to the skeleton. As you will see in the first image, the two controls (L_KNEE and L_LEG_POLE_VECTOR) move along with the leg just fine when I move the L_LEG_IK control when the skin is not bound. As soon as I bind the skin and move the L_LEG_IK control, the other controls mentioned no longer follow.

Why?

Before Bind


After Bind


Any help is greatly appreciated.

Thanks!
