title: Google spreadsheet scripts, Server error occurred. Please try saving the project again
body: <p>I have been using the same scripts in my Google sheets for a few years and today when a sheet is copied the onOpen function to create a custom menu fails to appear.</p>
  
  <p>If I attempt to run a function manually, I get an error, 'Server error occurred. Please try saving the project again.'</p>
  
  <p>The problem seems to be affecting all of my sheets with custom scripts when copied, the existing sheet function still works fine.</p>
  
  <p>Has anyone experienced this in the past 6 hours? Perhaps it is simply a Google server fault?</p>
