I have this bit of code for a subdivision function that is applied on a square:

extends CollisionShape2D

func _process(_delta):
    if Input.is_action_just_pressed("subdivide"):
        var oldExtents = shape.get_extents()
        var oldPosition =  get_position()

        queue_free() # removes the original block

        var topLeft = duplicate()
        get_parent().add_child(topLeft) # adds topLeft as a child of StaticBody2D
        topLeft.shape.extents = Vector2(oldExtents.x/2,oldExtents.y/2)
        topLeft.get_node("Sprite").scale = topLeft.shape.extents * 0.0316
        topLeft.set_position(oldPosition + Vector2(-oldExtents.x*2,-oldExtents.y*2))
        # set_pos(get_pos() + Vector2(-new_size/2, -new_size/2))

        var topRight = duplicate()
        get_parent().add_child(topRight) 
        topRight.shape.extents = Vector2(oldExtents.x/2,oldExtents.y/2)
        topRight.get_node("Sprite").scale = topRight.shape.extents * 0.0316
        topRight.set_position(oldPosition + Vector2(oldExtents.x*2,-oldExtents.y*2))

        var bottomLeft = duplicate()
        get_parent().add_child(bottomLeft) 
        bottomLeft.shape.extents = Vector2(oldExtents.x/2,oldExtents.y/2)
        bottomLeft.get_node("Sprite").scale = bottomLeft.shape.extents * 0.0316
        bottomLeft.set_position(oldPosition + Vector2(-oldExtents.x*2,oldExtents.y*2))

        var bottomRight = duplicate()
        get_parent().add_child(bottomRight) 
        bottomRight.shape.extents = Vector2(oldExtents.x/2,oldExtents.y/2)
        bottomRight.get_node("Sprite").scale = bottomRight.shape.extents * 0.0316
        bottomRight.set_position(oldPosition + Vector2(oldExtents.x*2,oldExtents.y*2))

        print(get_position())

Here's what currently happens when I click subdivide:

As you can see, it works fine the first division, but on the second division it only works on the top left corner. All the other corners get gradually smaller. On the third division I have no idea what's happening. So what can I do to get this to subdivide nicely?
