title: Cassette bundle not linking every stylesheet in the folder, only 1
body: <p>Here's how my folder is set up in Visual Studio 2010:</p>
  
  <pre><code>[solution]/Public
                /assets
                    /stylesheets
                        bootstrap.css
                        forms.less
                        main.less
                        tigo.less
  </code></pre>
  
  <p>I've set up some references because I want Bootstrap to appear first and forms and tigo have to appear after main.less.</p>
  
  <p>When I run this application on my local machine, this is the reference:</p>
  
  <pre><code>&lt;link href="/cassette.axd/asset/Public/assets/stylesheets/bootstrap.css?Fr-zb2zZgNbHEFtP2LHSlWzPcTc=" type="text/css" rel="stylesheet"/&gt;
  &lt;link href="/cassette.axd/asset/Public/assets/stylesheets/main.less?3YJKuT131pux5i9cKZkQeAO_qLQ=" type="text/css" rel="stylesheet"/&gt;
  &lt;link href="/cassette.axd/asset/Public/assets/stylesheets/forms.less?3j_M5YCMRn_e3APdf8XOLJrN9s0=" type="text/css" rel="stylesheet"/&gt;
  &lt;link href="/cassette.axd/asset/Public/assets/stylesheets/tigo.less?L6L9pztQ4BxBKmO_Q3XHBJx9L8Q=" type="text/css" rel="stylesheet"/&gt;
  </code></pre>
  
  <p><strong>It works fine on my machine.</strong></p>
  
  <p>However when publishing to AppHarbor, the references (minified) CSS file only contains the information from bootstrap.css</p>
  
  <p>Here is my configuration for Cassette:</p>
  
  <pre><code>namespace Foo.WebUI
  {
      /// &lt;summary&gt;
      /// Configures the Cassette asset bundles for the web application.
      /// &lt;/summary&gt;
      public class CassetteBundleConfiguration : IConfiguration&lt;BundleCollection&gt;
      {
          public void Configure(BundleCollection bundles)
          {
              bundles.Add&lt;StylesheetBundle&gt;("Public/assets/stylesheets");
              bundles.Add&lt;ScriptBundle&gt;("Public/assets/javascripts");
          }
      }
  }
  </code></pre>
  
  <p>And here is my _Layout.cshtml file:</p>
  
  <pre><code>@{
      Bundles.Reference("Public/assets/stylesheets");
      Bundles.Reference("Public/assets/javascripts");
  }
  &lt;!DOCTYPE html&gt;
  &lt;html&gt;
  &lt;head&gt;
      &lt;title&gt;@ViewBag.Title&lt;/title&gt;
  
      &lt;script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.1/jquery.min.js"&gt;&lt;/script&gt;
      &lt;script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.23/jquery-ui.min.js"&gt;&lt;/script&gt;
      &lt;link rel="Stylesheet" href="http://ajax.aspnetcdn.com/ajax/jquery.ui/1.8.10/themes/blitzer/jquery-ui.css" /&gt;
  
      @Bundles.RenderStylesheets()
  &lt;/head&gt;
  </code></pre>
  
  <p>Any ideas why it's not working correctly? Why is it grabbing bootstrap.css but forgetting about the other three files.</p>
