Creates TWO .css files in /build directory when using version

[wutmikee]

First off, thanks - saved many people some extra time building this.

Here's the code I'm running. This create/updates the public/build folder - however it adds TWO .css files when I use version. Creates a normal .css file in the build/css folder and then another .css file in the same folder that has the versioning.

Help?

elixir(function(mix) {
    mix.bower('app.css', 'public/css', 'all.js', 'public/js')
       .routes()
       .events()
       .phpUnit()
       .version('css/app.css');      
});

Sorry for not responding sooner.
I've read somewhere on the net that some people had problems with the 'version()' task, so maybe that's the problem here?
But I'll have a look as soon as possible!
I hope tomorrow.
