I solved the following problem I was instancing the shooter as a child of root not as a child of the current scene. Changed it and it now works,

I load a scene and it spawns a wave of marbles. Shooter tower is placed and shoots marbles.

It I reload the scene and I have tried several different ways the shooter tower is still shooting marbles even though he is not visible. You can see the marbles popping as they are shot- but the shooter tower is not present.

I tried to make a screen recording but it only recorded first scene not the current scene.

I assumed change_scene, reload_current_scene etc freed all nodes and left memory. But they are still running in background.

Could someone explain to me how to change or reload a scene and kill the previous scene so no unwanted instances are running?

here are methods I have tried:

#attempt 1
    func _on_restartButton_pressed():
    	print('restarted scene')
    	var scene = load("res://desertMap01.tscn")
    	var new_scene= scene.instance()
    	get_node("/root").add_child(new_scene)
    	queue_free()
      
 #attempt 2   
    func _on_restartButton_pressed():
    	print('restarted scene')
    	get_tree().reload_current_scene()
    	
  #attempt 3
    func _on_restartButton_pressed():
    	print('restarted scene')
       var error_code = get_tree().change_scene("res://desertMap01.tscn")
    	if error_code != 0: 
    		print("ERROR: ", error_code)

Thanks JB
