Occurs in 5.6.0b3. I'm just glad that it saves or whatever because I know I sure as hell forgot to save after five hours of work, lol.

This happened to me in version 5.5.2f1. Unity left open for at least a day or two without closing (computer on sleep overnight). Received this message after 8ish hours of use on the last day).
