Here it is Michael.
As You can see in the image link provided below with the disabled puzzle create rigid body dynamic, for the 3 wooden cubes, the scene is correct as you can see here:

If I enable the create rigid body, the cubes are placed somewhere above the walls and they are start falling when I refresh the scene, from somewhere above. Is the location set different when create rigid is set in the puzzles Mikhail ?
