Document version history
A coworker opened a file I'd been working on and said most of the text was missing. I checked the version history and found one where the text was all there. I attempted to restore that version, and I got an error that the version no longer existed. The page refershed an ALL the versions from the previous day (there were 3 or 4) had disappeared, and the only version available was the one that was partially completed. What happened to my other versions? Is there any way to restore them? It was hours of work.
