Multiple AUs

Hi, I ran into this same issue with 2007 and wanted to share how I fixed the issue in my title.I only had one AU and so I figured that something must be pointing to the title object. I did File->Export->XML and then opened up the exported XML file in an editor. Then I searched for "I cut the Test and pasted it somewhere else in my title. It reset the navigation action that when to my test, to now go to the title. I found the goto action, changed the target and then was able to publish. I will file a bug to get this fixed.Hopefully this will give you a way to debug the problem, sorry for the inconvenience.
