Okay so I have rigged many armatures in my time in blender, and this problem happens from time to time but its usually slight enough to ignore, but not this time. So I have a rig made for a human, with IK constraints and bones to manipulate them with. The constraints are applied to the shins, hips, upper, and lower arms. When I use the IK bones for the shins like lift them up and forwards it spasms and contorts twisting around.
Now I did remove the parents to all IK bones, and I just doubled check it before posting this. Also I don't know if this is part of the problem, but when I just raise the shins up the knees fly far out to the sides instead of just bending.
