Stephan,
Th is seems to be a serious flaw. I posted an update to my restoration of a classic model. After posting photos with rather detailed narratives. I realized the title of the update needed an edit update. After the initial post one was made I edited the title. The photos & narratives all disappeared. Ughhh!
Not a complaint, to me the new site is great. Just thought you would like to investigate.

The usual disclaimer is that of course it could have been an error on my part.
