Modify mesh problems

Question

Hello, I've recently asked myself how could I make a random planet and my quick answer was modify the verts of a sphere randomly, but now, it is taking a lot of pain.

after some research this is my code:

     Mesh mesh;
     Vector3[] verts;
     Vector3[] normals;
     Vector3 WorldPosition;
     void Awake(){
         mesh = GetComponent<MeshFilter>().mesh;
         verts = mesh.vertices;
         normals = mesh.normals;
         for (int i=0; i<verts.Length; i++) {
             verts[i] += normals[i] * Random.Range(1f,1.2f);
         }
         mesh.vertices = verts;
         mesh.normals = normals;
         mesh.RecalculateNormals ();
         mesh.RecalculateBounds ();
         mesh.Optimize ();
     }

I use it on a sphere and a plane to check if its correct, in the plane it seems that there is no problem. Plane before and after code:

But in the sphere something goes very wrong:

it seems like the verts are duplicating or something weird, I tried Mesh.Clear() but that doesn't work.

Anyone have an idea how I can fix it?

Thanks

After thinkin a few hours more this is my solution.

 for (int i=0; i<verts.Length; i++) {
             tempVert=verts[i];
             if(verts[i]!=initVerts[i]){ 
                 Debug.Log ("this vert has been already modified");
                 continue;
             }
             verts[i] += normals[i] * Random.Range(1f,1.2f);
             for(int j=0; j<verts.Length;j++){ 
                 if(i==j){ 
                     Debug.Log ("its the same vert");
                     continue;
                 }else{
                     if(verts[j] == (tempVert)){ 
                         Debug.Log ("Double vert");
                         verts[j]=verts[i];
                     }
                 }
             }
         }
