-		Turning on the option [b]Load As Placeholder[/b] for an instanced scene in the editor causes it to be replaced by an InstacePlaceholder when running the game.

 		The InstancePlaceholder does not have a transform. This causes any child nodes to be positioned relatively to the Viewport from point (0,0), rather than their parent as displayed in the editor. Replacing the placeholder with a scene with a transform will transform children relatively to their parent again.
