title: I deleted a React component that was never used, but now the page won't render... huh?
body: <p>I had a component in a ReactJS app I am working on that I sweeeearrr is not used anywhere. It even gave me the warning that "footer is defined but not used'. It isn't render anywhere and it never did anything, modify state... yet I'm getting an error message that says that the page cannot be rendered because the file is missing after I deleted it.</p>
  
  <p>Is this simply a matter that I must be missing a connection somewhere? </p>
