title: superclass mismatch error from class in Trailblazer operation when making changes to Rails code while server is running
body: <p>I'm using the <code>Trailblazer</code> gem with Rails, and there's a <code>Cell</code> class inside one of my <code>Trailblazer</code> operations that starts throwing a <code>superclass mismatch</code> error whenever I change the code with the server running.</p>
  
  <p>If I start the server and immediately start navigating the site, everything runs fine.</p>
  
  <p>However, if change some code any time after starting the server, and then try to load a page on the site, I get a <code>superclass mismatch</code> error.</p>
