title: _setting.scss file to import not found or unreadable in Foundation 6
body: <p>I've installed foundation 6 through foundation cli, and chose zurb-template. Everything is working ok when I run</p>
  
  <pre><code>foundation watch
  </code></pre>
  
  <p>From this moment, any file I change in src folder produces the reloading of the browser.
  The problem arises when I change anything in my own _settings.scss.</p>
  
  <p>The error message I get is:</p>
  
  <pre><code>Error in plugin 'sass'
  Message:
      src\assets\scss\app.scss
  Error: File to import not found or unreadable: settings
         Parent style sheet: 
  D:/wamp64/www/investoo_frontend2/src/assets/scss/app.scss
          on line 3 of src/assets/scss/app.scss
  &gt;&gt; @import 'settings';
     ^
  </code></pre>
  
  <p>My folder structure is:</p>
  
  <pre><code>my-project
      ├─ dist
      ├─ node-modules
          ├─ foundation-sites
          ├─ jquery
          ├─ what-input
          ├─ ...
      ├─ src
          ├─ assets
              ├─ js
              ├─ scss
                  ├─ _settings.scss
                  ├─ app.scss
  </code></pre>
  
  <p>In app.scss I am importing everything I need:</p>
  
  <pre><code>@charset 'utf-8';
  @import 'settings';
  @import 'foundation';
  @import 'motion-ui';
  @include foundation-global-styles;
  @include foundation-grid;
  </code></pre>
  
  <p>In config.yml I am using the right pahts:</p>
  
  <pre><code>PATHS:
  ...
    # Paths to Sass libraries, which can then be loaded with @import
    sass:
      - "src/assets/scss"
      - "node_modules/foundation-sites/scss"
      - "node_modules/motion-ui/src"
  </code></pre>
  
  <p>Any help?</p>
  
  <p>Thanks a lot.</p>
