Mismatched menu links go to new pages

The bug is in themes/opcv/js/opcv.js.
Around line 273 and 274 it looks like this:

jQuery('.menu-343 a').attr('href', '#work');
jQuery('.menu-342 a').attr('href', '#about');

Now just go back to the front page and view the source code, you should find something like:

<div id="navigation">
  <div class="section">
    <ul id="main-menu" class=""><li class="menu-239 first active"><a href="/" class="active">Home</a></li>
      <li class="menu-357"><a href="/work">Work</a></li>
      <li class="menu-356"><a href="/about">About</a></li>
      <li class="menu-240 last"><a href="/contact">Contact</a></li>
    </ul>
  </div>
</div>

You should modify opcv.js and change it to:
jQuery('.menu-357 a').attr('href', '#work');
jQuery('.menu-356 a').attr('href', '#about');
