5.4.4 Layered "IK" Modular Control Rig broken?

Hello, is the Layered “IK” modular Control Rig broken? When I turn on Layered “IK” Modular Control Rig, the COG is no longer connected to the rest of the Modular Control Rig.

  1. I create a Modular Control Rig on a skeleton.

When I move the COG down, the torso comes along with the COG correctly.

  1. I open Sequencer and drag in a skeleton. Then plug in an animation clip.

  1. In Sequencer, turn on Layered “IK” Control Rig.

  2. See the COG is no longer connected to the rest of the Modular control Rig.

  3. “Important” The COG problem only happens when I have an anim clip on a skeleton then turn on ‘Layered’ and choose the “IK” Modular Control Rig. The “IK” COG works fine if there is no anim clip in Sequencer.

Is there a way to have the Layered “IK” Control Rig?
