title: Why would a step function cancels itself when there are no errors
body: <p>I have a step function (illustrated below) and I was working out the few remaining issues when all of a sudden I hit a rather unexpected result:</p>
  
  <ul>
  <li>All tasks that have completed, completed successfully without error</li>
  <li>All remaining tasks simulateously cancel themselves (also no error)</li>
  </ul>

  <p>I'm a bit dumbfounded. Has anyone seen this? Does anyone know how I'd go about troubleshooting it?</p>
