The AI rewrote one of my own chapters. Where is my original text?

From version 1.9.21, before the AI rewrites a chapter you wrote yourself, BookyAI saves your text as "Your original" in that chapter's Versions panel. Open the chapter in the editor and press Versions: "Your original" is listed after the other versions, and you can read it or put it back. It is kept for good: unlike the other versions, which keep only the latest ten, your original is never removed, however many times the chapter is rewritten afterwards. Putting your original back also removes the chapter's "AI rewrite" mark.
