This behavior started recently where documents that had workflow approval (2010) flagged with the value 16 (approved) stopped protecting that.
By that I mean I could edit the file and the approved bit (not the approval status) did not vanish.
Previously (last week) if I replaced the file or edited it in ANY way the approved flag was gone immediately. I assume this to be because the version I am now working with has not had the bit tripped (16).
What could have caused this function to start failing? I now have a potential audit concern that documents could b edited after approval.
