title: Library with identifier LabelServices is missing (perhaps it was deleted?) / Something went wrong. Please reload
body: <p>I have posted this on google-apps-script-issues (<a href="https://code.google.com/p/google-apps-script-issues/issues/detail?id=4723&amp;can=4&amp;colspec=Stars%20Opened%20ID%20Type%20Status%20Summary%20Component%20Owner" rel="nofollow">https://code.google.com/p/google-apps-script-issues/issues/detail?id=4723&amp;can=4&amp;colspec=Stars%20Opened%20ID%20Type%20Status%20Summary%20Component%20Owner</a>) but with no response I am getting desperate as all my sheets and scripts are breaking down. So I hope someone here might have encountered this and have some idea for me how to handle this.</p>
  
  <p>Some of my exiting scripts (including some in spreadsheets) suddenly started throwing the exception 'Library with identifier LabelServices is missing (perhaps it was deleted?)'.</p>
  
  <p>I tried deleting the library reference in some of the scripts that were throwing this error and re-adding it but the same error comes up. I even defined a new library with the same name and try to use it instead. Still the same error. </p>
  
  <p>Most likely a related error, when trying to open project properties to these scripts I see the message 'Something went wrong. Please reload.' and the hourglass never stops. This happens at both standalone scripts and ones embeded in spreadsheets.</p>
  
  <p>Please note that if I add the same library to a new script then there is no problem and the library works perfectly.</p>
  
  <p>I would like to add that even if I remove the library and also any calls or references to the library the problem still persists.</p>
  
  <p>Link to a script where this happens is available at <a href="https://script.google.com/d/1ptevXwu25z9Vo88zX0XOyaQk5pE5MmzwDbb-lMglNY1lzz1HBBiAeJxn/edit?usp=drive_web" rel="nofollow">https://script.google.com/d/1ptevXwu25z9Vo88zX0XOyaQk5pE5MmzwDbb-lMglNY1lzz1HBBiAeJxn/edit?usp=drive_web</a>
  You can copy it and play with it. You should get the same problem.</p>
  
  <p>Appreciate any help!!!</p>
