The automation is fairly simple. In your workflow add a step that checks to see if the criteria “Ticket Status has been closed”. This checks to see if the ticket was ever closed in the past. Then if it had a closure in the past the ticket will go to Closed again. There is a down side, if you want to force a ticket back open it gets a little tricky but this kills the Zombies really well.
See if this image works better than the last one I posted.
