Unity doesn’t allow you to add components in OnDestroy, because then when the game is shutting down more components are created. When the parent object is destroyed, its children are destroyed as well, at which point we try to add components to parent, which doesn’t give a nullreference, but the object IS already destroyed.

What you should do is call AddGameOver from the parent just after you Destroy the child. That way it will not be called when the game shuts down.
