Setting a mesh's triangles and vertices from file causes distortion.

Hi, I am trying to load a mesh from a text file that contains the vertices and triangles, but when applying the values to the mesh filter, the mesh becomes blocky. The object is saved after the changed and then can be loaded. The first image below is the original object before it is loaded and the second is after it is loaded. I also have included the save and load C# script.

Thanks

 using UnityEngine;
 using System.Collections;
 using System.IO;
 using System.Collections.Generic;
 public class save : MonoBehaviour {
     public GameObject planet;
 
 
     void Start()
     {
 
     }
     public void Save()
     {
         System.IO.StreamWriter file = new System.IO.StreamWriter(Application.dataPath + @"\pl128.txt");
 
         for(int i = 0; i < planet.GetComponent<MeshFilter>().mesh.vertices.Length; i++)
         {
             file.WriteLine(planet.GetComponent<MeshFilter>().mesh.vertices[i]);
         }
         for(int i = 0; i < planet.GetComponent<MeshFilter>().mesh.uv.Length; i++)
         {
             file.WriteLine(planet.GetComponent<MeshFilter>().mesh.uv[i]);
         }
         for(int i = 0; i < planet.GetComponent<MeshFilter>().mesh.triangles.Length; i++)
         {
             file.WriteLine(planet.GetComponent<MeshFilter>().mesh.triangles[i]);
         }
 
 
         file.Close();
     }
 }
