[Unity] mesh memory leak

I'm not sure if it's the way I'm using it or if the spine-unity runtime that is causing the issue but I've noticed while using the profiler that when I destroy a gameobject that has a SkeletonRenderer that it will leak the mesh.

First I made a spine prefab. In code I will use it like so:

GameObject go = (GameObject)Resource.Load("someObject");
SkeletonAnimation skelAnim = go.GetComponent<SkeletonAnimation>();
skelAnim.state.SetAnimation(0, "someAnim", true);

// later when I'm done with it
GameObject.DestroyImmediate(go);
//the mesh data has now leaked.

I ended up adding a Destroy function to the SkeletonRenderer.cs and I call this before GameObject.DestroyImmediate and I no longer get any leaks.

public void Destroy()
   {
      if (meshFilter != null) meshFilter.sharedMesh = null;
      if (mesh != null) DestroyImmediate(mesh);
      

  if (mesh1 != null) DestroyImmediate(mesh1);
  if (mesh2 != null) DestroyImmediate(mesh2);
  
  if (renderer != null) renderer.sharedMaterial = null;
  mesh = null;
  mesh1 = null;
  mesh2 = null;
  lastVertexCount = 0;
  vertices = null;
  colors = null;
  uvs = null;
  sharedMaterials = new Material[0];
  submeshMaterials.Clear();
  submeshes.Clear();
  skeleton = null;
   }

I also noticed that in the Reset function you are only destroying mesh and not mesh1 or mesh2, it seems like this is a leak as well because you have "mesh1 = newMesh(); mesh2 = newMesh();" and mesh just looks to point to one of them.

whoa.. this is exactly what i'm facing right now..
i got scold by my boss because of the game is laggy .__.
i know the SkeletonAnimation is the problem, but have no idea what i need to do :v

i will try your solution 😃 thanks a lot sir~

GameObject go = (GameObject)Resource.Load("someObject");

Just to be clear... this does not spawn an instance of "someObject", it only prepares it to be instantiated... just making sure thats not what people think is going on here.
