title: Xcode keeps expanding all groups in the project navigator
body: <p>Since a couple days ago Xcode keeps expanding all the groups and subgroups in the project navigator.</p>
  
  <p>I have repeatedly collapsed them so I can focus on what I'm working on and then I go back and they're all expanded again.</p>
  
  <p>Has anyone else experienced this?</p>
  
  <p>I collapse a group, move to a different tab in Xcode and then back and the groups are all expanded again.</p>
  
  <p>It's really frustrating as I keep losing track of the files I'm working with.</p>
