Replace a chapter?
What would be the easiest way to replace a chapter that is poorly formatted? I have a 26 chapter book that is okay except for one chapter which was poorly formatted. I have "cleaned it up" in word, and have checked it on the Kindle Previewer, and now it is fine. My question is now, is there a way to substitute this newly corrected chapter in Sigil? Or, will I have to start over and lose all my formatting of the other 25 chapters that I did in Sigil? Thanks to anyone who can help me.
