Error when combining meshes

I got an error when I was combining meshes:

The piece of code this error refers to is:

Mesh combinedMesh = new Mesh();
combinedMesh.CombineMeshes(combine, true, true);

I am using Unity 2017.2 beta

Is this a bug?

You should probably best ask this in the thread of this asset.
My best guess is that you are trying to combine meshes with too many poly’s when added up.
Limit is about 65k polys per mesh.

It’s an asset I created myself. That what my guess too, I’ll test some things and see if that’s indeed the issue!
