The collision with meshes appear to be broken in relation to parent and a grandchild or great grandchild collision boxes.
Results: The collision meshes do not move with the visible static meshes. The problem runs both ways - both up and down the parent-child-grandchild-greatgrandchild and up again.
Expected: The collision meshes should move along with the static meshes.
