title: AWS EB Error: Incorrect application version found on all instances
body: <p>I am trying to use the EB CLI to deploy an application into an environment but I seem to be getting strange errors. Is there a way to empty out previous application versions so I can upload a fresh application?</p>
  
  <p>The message I see after I execute eb deploy.</p>
  
  <pre><code>Update environment operation is complete, but with errors. For more information, see troubleshooting documentation.
  </code></pre>
  
  <p>I am currently getting this error:</p>
  
  <pre><code>Incorrect application version found on all instances. Expected version [app version]
  </code></pre>
  
  <p>The logs file also seems to be getting deleted for some reason.</p>
