Citizen: elbow & kneecap helpers now cooperate with stretching/squashing limb lengths limbs The elbow helpers are now children of the lower arm bones, and the kneecap helpers are now children of the lower leg bones. The procedural constraints were then adjusted accordingly. This makes stretching/squashing limb lengths work properly, and without needing animation sequences to hold helper position data... which didn't exist, and was set to be ignored anyway.
