problem with prefab Instantiate and cameras

hi guys and girls

i need help,

So, i Instantiate a prefab with a couple of game objects inside namelly 4 Cameras.
my problem is not getting the prefab or getting the cameras the problem is that whem i cicle through the cameras they change the transform value to the last camera i was in, the strangest part is that after i close the game the camera possition in the prefab are all so changed to the value of the last camera i was in, so the next time i run the game all the cameras have the same possition

all the code i have regarding the camera problem is below

Code (csharp):

1.  
2.         mapa_de_jogo = PlayerPrefs.GetString("mapa_de_jogo");      
3.         mapa = (GameObject)Resources.Load(mapa_de_jogo, typeof(GameObject));
4.         Instantiate(mapa, new Vector3(0, 0, 0), Quaternion.identity);
5.  
6.         //possicao inicial da camera
7.         cam_pos = new  Transform[4];
8.  
9.  
10.         cam_pos [CAM_INI] = mapa.transform.FindChild("Camera Inicial");
11.         cam_pos [CAM_JOGO] = mapa.transform.FindChild("Camera Combate");
12.         cam_pos [CAM_DIR_TURNO] = mapa.transform.FindChild("Camera Right");
13.         cam_pos [CAM_ESQ_TURNO] = mapa.transform.FindChild("Camera Left");
14.      
15.         // "Camera Right" "Camera Inicial" "Camera Combate" "Camera Left"
16.         cam_index = CAM_INI;
17.         cam_cur_pos.position =  cam_pos[cam_index].position;
18.         cam_cur_pos.rotation =  cam_pos[cam_index].rotation;
19.         cam.transform.rotation = cam_cur_pos.rotation;
20.         cam.transform.position = cam_cur_pos.position;
21.  
22.  

Code (csharp):

1.  
2.  
3.  void Update()
4.     {
5.  
6.         if (cam_ani_inicial)
7.         {
8.             if (cam_index == CAM_INI)
9.             {                
10.                 if(cont == 64)
11.                 {                  
12.                     cam_index = CAM_JOGO;
13.                 }
14.                 cont++;
15.             }
16.             if(cam_cur_pos.position.y - cam_pos [CAM_JOGO].position.y <0.1)
17.             {
18.                 b_get_ready = true;
19.             }
20.             if (cam_cur_pos.position == cam_pos [CAM_JOGO].position)
21.             {
22.                 cam_ani_inicial = false;
23.                 b_get_ready = false;
24.             }
25.         }
26.                
27.         //control da camera
28.         cam_cur_pos.position = Vector3.Slerp(cam.transform.position, cam_pos [cam_index].transform.position, Time.deltaTime * smooth);
29.         cam_cur_pos.rotation = Quaternion.Slerp(cam.transform.rotation, cam_pos [cam_index].transform.rotation, Time.deltaTime * smooth);
30.        
31.         cam.transform.position = cam_cur_pos.position;
32.         cam.transform.rotation = cam_cur_pos.rotation;      
33.     }
34.  
35.  

 

i post my own solution its the bit of code marked by [SOLUTION]

Code (csharp):

1.    
2.        mapa_de_jogo = PlayerPrefs.GetString("mapa_de_jogo");
3.         string str = mapa_de_jogo + "(Clone)";
4.         mapa = (GameObject)Resources.Load(mapa_de_jogo, typeof(GameObject));
5.       [SOLUTION]  GameObject go[/SOLUTION] = Instantiate(mapa, new Vector3(0, 0, 0), Quaternion.identity) as GameObject;
6.         //possicao inicial da camera
7.         cam_pos = new  Transform[4];
8.         cam_pos [CAM_INI] = go.transform.FindChild("Camera Inicial");
9.         cam_pos [CAM_JOGO] = go.transform.FindChild("Camera Combate");
10.         cam_pos [CAM_DIR_TURNO] = go.transform.FindChild("Camera Right");
11.         cam_pos [CAM_ESQ_TURNO] = go.transform.FindChild("Camera Left");
12.      
13.         // "Camera Right" "Camera Inicial" "Camera Combate" "Camera Left"
14.         cam_index = CAM_INI;
15.         cam_cur_pos = cam_pos [cam_index];
16.         cam.transform.rotation = cam_cur_pos.rotation;
17.         cam.transform.position = cam_cur_pos.position
