I have an Umbraco 4.7.1.1 site that has mysteriously lost its Content and Properties data for one specific data type. The data type is complete in Settings / Document Types, but when viewed in the Content Tree, there is no content. See link for screenshot: Screenshot
The data was uploaded using CMS Import and has been live on the site for months now but just now starting showing this issue. I've tried republishing the content and cycling the App Pool, to no success. Ideas?
