title: Remote branches are no longer being tracked
body: <p>We're using <code>SourceTree</code> to create our feature branches and push local code up to our repos in BitBucket. In the past two weeks we have started getting errors in Jenkins when switching branches.</p>
  <p>Investigating the error leads to an error from Git about tracking not being setup:</p>
  <blockquote>
  <p>There is no tracking information for the current branch</p>
  </blockquote>
  <p>This has now happened for feature branches from <strong>3</strong> different developers. I am thinking an update to SourceTree perhaps caused some setup change locally where branches are no longer being tracked on creation.</p>
  <p>Looking through older questions on SO, this seems different due to no active changes being made in our local dev enviornments.</p>
  <p>I tested creating a new feature locally and pushed it. When I switched code manually I did not get any tracking errors, which seems to further indicate a setup issue.</p>
  <p>If anyone is knowledge on SourceTree or default Git options for tracking, or have insight on why those options may have been changed or reset, I would appreciate it. Thank you.</p>
