Why do my objects spawn in twice?

Mycoal

For some reason, every time a new player joins, it clones the tile gameObject again, resulting in 2 sets of tiles no top of eachother.

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using Photon.Pun;
using UnityEngine.SceneManagement;

public class GridManager : MonoBehaviourPunCallbacks
{

  [SerializeField] private int _width, _height;


  [SerializeField] private Tile tilePrefab;

  [SerializeField] private Transform cam;

  public bool spawnedIn = false;

  public PhotonView pv;
  public GameObject holder;
  private bool start = true;
  private void Start()
  {
    if(PhotonNetwork.IsMasterClient)
    {
      if(spawnedIn == false)
      {
        pv.RPC("generateTile", RpcTarget.AllBuffered);
      }
    }
  }


   

  [PunRPC]
  void generateTile()
  {
    if (!spawnedIn)
    {
      //pv.RPC("setFalse", RpcTarget.AllBuffered);
      for (int x = 0; x < _width; x++)
      {
        for (int y = 0; y < _height; y++)
        {
          var spawnedTile = PhotonNetwork.Instantiate(tilePrefab.name, new Vector3(x, y), Quaternion.identity);
          spawnedTile.transform.parent = holder.transform;
          spawnedTile.name = $"Tile {x} {y}";
          spawnedIn = true;

          if (x > 7)
          {
            spawnedTile.gameObject.layer = 24;
          }
          else
          {
            spawnedTile.gameObject.layer = 23;
          }
          spawnedTile.GetComponent<Tile>().lane = y;
          if (start)
          {
            spawnedTile.GetComponent<Tile>().plantSelect = true;
            start = false;
          }
          var isOffset = (x % 2 == 0 && y % 2 != 0) || (x % 2 != 0 && y % 2 == 0);
          spawnedTile.GetComponent<Tile>().init(isOffset);
        }
      }
    }
       
    cam.transform.position = new Vector3((float)_width / 2 - 0.5f, (float)_height / 2 - 0.5f, -10);
    cam.transform.position = new Vector3(cam.transform.position.x, cam.transform.position.y + .55f, cam.transform.position.z);
    //PhotonNetwork.Destroy(gameObject);
  }


  [PunRPC]
  public void setFalse()
  {
    spawnedIn = true;
  }
}

This is the only script that actually spawns in the tiles. Thank you for helping!

You call the RPC on all clients. Each of your players will then spawn the tiles and network-instantiate them, which means everyone will see everyone's tiles.
