After picking Automatic code signing, it will crash while packaging the app. Anybody else?

Pertinent system prefs: [X] Ask to keep changes when closing documents [ ] Close windows when quitting an app App setup: autosavesInPlace returns true I've run my app many times and have one test doc that I use each time I run via it being automatically reopened. Recently I created a couple new documents, then closed them before quitting and used the Delete button to dispose of them. Yet each time I run, all the supposedly deleted docs reappear. They're not being deleted from "/Users//Library/Containers//Data/Library/Autosave Information/". Why?
