Commented Unassigned: Page does not load, IISExpress cpu usage climbs [69]

I recently installed the Sass bundle transformer through Nuget and converted our bundler to use it:

```
var styleBundle = new Bundle("~/Styles/all");
styleBundle.Include("~/Styles/Toastr/toastr-2.0.1.css")
.Include("~/Styles/site.scss");

styleBundle.Builder = new NullBuilder();
styleBundle.Transforms.Add(new CssTransformer());
styleBundle.Orderer = new NullOrderer();

bundles.Add(styleBundle);
```

However, when I try to browse to the site, the site never loads, and the CPU usage of IIS Express goes very high. IIS Express reports a 401.2, but browser side there is never a response, and it constantly awaits a server response.

I'm using angularjs, if that's relevant.
Comments: Hello, Moogleii! I can not say anything definite until I see contents of the `~/Styles/site.scss` file. BundleTransformer.SassAndScss have performance problems and I have already talked about them in the ["sass minification too slow - caching?"](https://bundletransformer.codeplex.com/discussions/460875) discussion.
