title: Godot engine: removing an instance of a scene without freeing the whole scene
body: <p>I’ve added multiple instances of a scene as enemies, and now I want to remove one of them when it dies. I tried using “queue_free()” on it, but this only works for one instance, and every instance afterwards doesn’t get removed and returns a “node not found” error. How do I just remove one instance at a time?</p>
