Several of our process models in development have been corrupted: text boxes are missing and the angle connectors have all changed to straight connectors. So far the damage looks to be isolated to one folder. I have attached a section of our app server log. Any ideas what would cause this? Our system admin did not find any issues. The only mistake we know we made was that we changed the name of a constant and deleted the old one and forgot to change the constant name in our PM before running it. thanks in advance....
