title: Fatfree framework route not found
body: <p>I am using the fatfree framework and it now happened several times that suddenly a route is not found anymore. Calling the route will result in a 404. If I rename the route without doing any additional changes it is being found again. 
  There are no concurrent routes as I am just using simple ones such as:</p>
  
  <pre><code>$f3-&gt;route('GET|POST /test',
      function($f3) use ($db){ ... });
  </code></pre>
  
  <p>Calling /test will result in a 404. Emptying browser cache or using a different browser does not help. If I change the code to e.g.:</p>
  
  <pre><code>$f3-&gt;route('GET|POST /test2',
      function($f3) use ($db){ ... });
  </code></pre>
  
  <p>It will be working fine using /test2 . </p>
  
  <p>It worries me a lot that this is happening totally at random and that I have not found any way to fix the old route other than to rename it.</p>
  
  <p>Is it possible to clear a routing related cache of f3 or similar which might solve the problem?</p>
