Here's one way to reproduce it: http://screencast.com/t/4pJ5Ewn6d9oh
1. Validate that Website Properties in Area settings is pointing to a valid item type
2. Go into MC and edit that web site settings type. In my video I am deleting a field.
3. Edit the area settings again. In some cases, the item types were empty immediately (when clicking Item Type). In the video I had to bring up the Permissions dialog first before they would be cleared. Not sure if that matters.
4. Hit Save and Close. Since no items types are selected, the data gets deleted from the database.
Normally, when you manually unselect an item type you get a warning about the loss of data. However, in this case since the items aren't either selected to begin with or are deselected using JavaScript the warning never comes up and you lose your data.
Happy to supply a backup of this site if needed.
