We're using K2 2.4 in a Joomla 1.5 installation. We have a tour company and each tour has related information for each tour presented in tabs: Description, Itinerary, Rates, Map, etc.

Recently we were changing our menu structure and also adding some subcategories that a set of existing tours were switched to. After we were done with the restructure, we were shocked to find that much of the existing content in each tour was gone!

The Description tab's content was fine, as was a couple of others, such as a video that was posted on each, but the Itinerary, Rates, Vessel were blank on both the frontend and in the backend. We had no choice but to try to reconstruct the data, a long process.

Anyone have any idea what we did that might have caused this content to disappear and if there would be any way to get it back?
