    I had clone physics world from BuildPhysicsWorld.PhysicsWorld, assign it back to BuildPhysicsWorld.PhysicsWorld after few step and nothing change.
    Do I also need to clone Translation, Rotation data for rollback?

    It's best you clone the ECS data, not physics runtime data, since physics runtime data is created based on ECS data each frame in BuildPhysicsWorld, so it probably gets overwritten in your case.
