Prefabs missing on reload

Hi everyone,

I just got my little game to function right from beginning to end, and now I'm trying to make reloading the scene work. When I $$anonymous$$t the button to reload, the prefabs I had in the scene mysteriously vanish. I'm currently using v5.3 and the SceneManager script to reload the scene. They are still present in the $$anonymous$$erarchy, but they do not exist in the game proper. If anyone has any suggestions as to what is causing t$$anonymous$$s and what can be done to rectify the situation, I would be most appreciative. Thanks in advance.
