title: Renamed Heroku's hostname, now it can't find the application
body: <p>I previously had my Heroku's application name at:</p>
  
  <p>shielded-meadow-9293.heroku.com</p>
  
  <p>This was the name when I created the Heroku remote and fired up the dyno. After everything was running smooth, I changed the name to </p>
  
  <p>platformdesignmadness.heroku.com</p>
  
  <p>The site works, but in the same terminal, when I do a command such as </p>
  
  <p><code>heroku ps</code></p>
  
  <p>I get a <code>$&gt;  !    Couldn't find that app.</code> error. Why is this? </p>
