I've had a few reviews "disappear" on me while editing and I'm worried that sooner or later it's going to lead to disaster. It has not become an issue so far because I usually make a copy of the original review in notepad, so if something disappears, I paste it back in and edit again. However, I started working on an extended format review this afternoon (which needed to be be copy & pasted in sections ) and I forgot to save one section , and when I clicked "save" after editing, I got a message saying the now empty section "is required." Navigating back re-populated the field, but it was a close call.

Has this happened to anyone else?
