Script not included in Build?

I’m trying to import an OBJ at runtime with this asset:

It works greate in the editor but I can’t get it to run in the Standalone Build.
I would like to test if the OBJLoader.cs is even part of the build.
Is there any way I can do that?
Maybe some ideas why the asset isn’t working in a standalone build?

All scripts that aren’t editor scripts should be included in the build. I haven’t looked at the script, but you can always add debugs to it and use log viewer https://www.assetstore.unity3d.com/en/#!/content/12047 to view the console in the standalone build, which should also help you track down any errors you may be getting.
