public static string playerPrefab = "/GameStuff/Prefabs/PlayerPrefab";

Object pl = Network.Instantiate(Resources.Load(playerPrefab),
            new Vector3(0, 0, 0), Quaternion.identity, 0);

The only error I am getting is NullReferenceException, I figure this means that Resources.Load is unable to find my prefab, which is located in \Assets\Resources\GameStuff\Prefabs\PlayerPrefab.prefab. I've tried with \ instead of / etc.
