I'd just put in roughly 50 lines of tasks in a new sheet. Hadn't manually saved it, yet. Power blipped out for a few seconds. After everything loaded back up, EVERYTHING was gone from the sheet.
I checked my Personal settings under Account. It was set to auto-save after 3-minutes of inactivity and also to auto-save when the sheet was closed. Since I was working constantly and hadn't closed my sheet, I guess I didn't meet either of these criteria. I've never met a program that depends on your INactivity to auto-save. But that's beside the point at the moment, although it should be changed to just auto-save PERIOD after a certain amount of time.
So is there any way to recover my work? There's nothing in the Deleted Items folder in the Home tab, although that doesn't surprise me. My sheet is just blank. Is there anything I can do to get my stuff back?
