title: Django not picking up new changes
body: <p>I'm running an old branch A from my GitHub repo, and Django is not picking up any of the static files. What's weird is that if I make any text changes to the templates, it doesn't pick those up either. I've tried refreshing the page, opening Chrome in Incognito, restarting the server, etc. -- nothing is working.</p>
  
  <p>After running the development server in a different branch B, and switching back to this one, Django acted as if I was still running on branch B (got not 404 errors):</p>
  
  <pre><code>$ ./manage.py runserver
  0 errors found
  Development server is running at http://127.0.0.1:8000/
  Quit the server with CONTROL-C.
  [12/Sep/2012 23:25:48] "GET /interviews/ HTTP/1.1" 200 13295
  </code></pre>
  
  <p>But as soon as I restarted the server, it reverted to the un-changed version of branch A (none of the changes were picked up and no static files could be found):</p>
  
  <pre><code>$ ./manage.py runserver
  Validating models...

  <p>Between the two branches, settings.py and the static folder are identical so I'm not even sure where to begin with troubleshotting.</p>
