Unity [PUN] New Instantiated players cannot see previously instantiated players

Hello, i have recently worked on a game, but now i have this error where a new instantiated player cannot see previously instantiated players, but previously instantiated players can see newly instantiated players. There are also no error messages or warning messages in the console, though i got some previously that just magically dissapeared. It was something like failed to (something) on serilization with id 1001 ignore this if you are leaving a server.

I have 2 scenes, one called LobbyMenu and one called Game.

This script is mounted in the Game scene: using UnityEngine; using System.Collections; using UnityEngine.SceneManagement;

public class GameManager : Photon.MonoBehaviour {

 public string playerPrefabName = "FPSController";
 public Transform SpawnPoint;

 void Start()
 {
     if (PlayerManager.LocalPlayerInstance == null)
     {
         GameObject pl = PhotonNetwork.Instantiate(playerPrefabName, SpawnPoint.position, SpawnPoint.rotation, 0) as GameObject;
     }
 }

 public void OnLeftRoom()
 {
     SceneManager.LoadScene(0);
 }

 public void LeaveRoom()
 {
     PhotonNetwork.LeaveRoom();
 }
 

}

This second script is mounted in the LobbyMenu scene:

using UnityEngine; using UnityEngine.UI; using UnityEngine.SceneManagement;

public class Launcher : Photon.MonoBehaviour { const string VERSION = "1"; public string roomName = "iskrem"; public string playerName; public Text input; public Text nameInput; public GameObject connect; public GameObject roomInfo; public GameObject NameInput;

 void Start()
 {
     PhotonNetwork.ConnectUsingSettings(VERSION);
     roomInfo.SetActive(false);
     NameInput.SetActive(false);
     connect.SetActive(true);
 }

 void OnGUI()
 {
     GUILayout.Label(PhotonNetwork.connectionStateDetailed.ToString());
 }


 public void ChangeRoom(int value)
 {
     if(value == 0)
     {
         roomName = "server 1";
     }
     else
     {
         value = 0;
     }
 }

 public void RoomSelect()
 {
     OnJoinedLobby();
 }

 public void ConnectToRoom()
 {
     roomName = input.text;
     OnJoinedLobby();
 }

 public void Spawn()
 {
     PhotonNetwork.LoadLevel(1);
 }

 public void NameSelected()
 {
     playerName = nameInput.text;
     roomInfo.SetActive(true);
     NameInput.SetActive(false);
 }

 void OnJoinedLobby()
 {
     RoomOptions roomOptions = new RoomOptions() { IsVisible = false, MaxPlayers = 4 };
     PhotonNetwork.JoinOrCreateRoom(roomName, roomOptions, TypedLobby.Default);
     print("Successfully Joined or Created" + roomName);
 }

 void OnJoinedRoom()
 {
     NameInput.SetActive(true);
     connect.SetActive(false);
 }

}

This last script is mounted on my player: using UnityEngine; using System.Collections; using UnityStandardAssets.Characters.FirstPerson;

public class PlayerManager : Photon.MonoBehaviour {

 public GameObject Camera;
 public static GameObject LocalPlayerInstance;

 public void Awake()
 {
     // #Important
     // used in GameManager.cs: we keep track of the localPlayer instance to prevent instanciation when levels are synchronized
     if (photonView.isMine)
     {
         LocalPlayerInstance = gameObject;
     }

     // #Critical
     // we flag as don't destroy on load so that instance survives level synchronization, thus giving a seamless experience when levels load.
     DontDestroyOnLoad(gameObject);
 }

 void Start ()
 {
     if (!photonView.isMine)
     {
         Camera.SetActive(false);
         GetComponent<RigidbodyFirstPersonController>().enabled = false;
     }
 }

}
