During power outages or small breaks, I tend to set my PC to sleep mode. This is a common workflow that I have, I usually do that once every two days. Fortnite will end the session you are in and put you on the main menu lobby, however UEFN will completely freeze if that happens during the push to live edit (which takes a lot more time now) and I have to restart the editor if it happens. Essentially an interruption to that process can cause the editor to freeze.
