title: Heroku missing some changes after deploy
body: <p>I've pushed some commits to Heroku and after getting an error and running <code>heroku run bash</code>, I see that some files are missing/have not been deployed. I think this might be due to some rebasing/pushing cycles I done before this deploy. I've already set up some addons so I'd like to avoid creating a new app and starting from scratch.</p>
  
  <p>Is there an alternative way?</p>
  
  <p>Edit:</p>
  
  <p>The gist of what I did:</p>
  
  <ol>
  <li><code>rebase</code></li>
  <li><code>push -f</code></li>
  <li>see errors on deploy..</li>
  <li>more <code>rebase</code>-ing</li>
  <li><code>push -f</code></li>
  <li>see that files are missing from Heroku build</li>
  </ol>
