It happened to all of us back in January. Mangago's data disk crashed. Only stories you have rated and/or tagged were recovered, nothing else did or will come back. All retrieved stories were dumped into your "Already read" list, you have to manually re-add them back where they were pre-crash. You can start rebuilding your lists now.
I have been inactive for a while and everything is gone
