The perp. Goes by the moniker Moonlight.
I’m sure every writer has either had this happen, or had nightmares of it happening: You finish up a nice bit of work and walk away from the computer. Do you think about the havoc your cat can wreak on your work? No, you do not. And when you return, hours later, having forgotten all about it, you find gibberish on the screen in place of your finely turned prose.
Yeah, it happened to me. Look at Moonlight. Doesn’t she look innocent and cuddly? Well, cuddly she is, but innocent she is not. No, this kitty tried to rewrite my chapter for me. Bad kitty! Seriously, she’s a terrible writer. Here’s a sample: [[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[… What kind of writing is that?
Yes, of course I had saved my work. (How stupid do you think I am? No, on second thought…) I saved, and furthermore, it was backed up automatically to Dropbox. What I failed to do, though, was to close Scrivener before I walked away. Scrivener auto-saves anything you write. So your cat dances on your keyboard (or parks her fuzzy butt on it for warmth), and Scrivener obligingly saves all her new work for you. And the new work gets saved to Dropbox!
That’s what I found when I came back to my laptop, hours later.
What to do? Dropbox’s “deleted versions” to the rescue! I went online to my Dropbox account and looked for the mostly recently changed file in my Scrivener folder. (That took a little while, owing to the spaghettified file structure of my book, but never mind that.) Scrivener saves each chapter as a little rtf file, and sure enough, the last-saved file was time-stamped half an hour after I left the house! Caught you, you little scalawag!
Dropbox saves a number of older versions. It’s not even remotely obvious how to find them, but I eventually discovered if you click on the file you want, then click the little icon with three dots at the top, it offers to show you the version history. And there’s where you find your pre-cat-dancing version, and restore it to its rightful place.
Hah! Show you, you little furball!
