I've been saving my site as a template successfully for a while, but after adding a new dialog to my 'Action Items' list in SharePoint Designer, I am no longer able to export my site.
The original error said the problem was with my Action Items list, however when I deleted that it just changed the message to the next list alphabetically. There is nothing in the Logs about this failure.

I found this suggestion about deactivating content types but it made no difference. There is also no correlation Id given, and I get the same error when I try to export it from powershell. Does anyone know what to do?
