Thanks for the thoughts. I opened the file and it had a bunch of errors, so I ran the Epub to Epub conversion. Now when I open the file in the editor, it doesn't find errors, but the same bits of text are missing.
I found the spot where three paragraphs are missing in front of an ornamental break, and I can't see anything wrong that's obvious to me (all the tags seem to have an open and a close, which is all that I'm 100% sure about.) I know this isn't as easy to read without all the colours, but if someone can point out to me what the problem is, so I know what to look for, that would be greatly appreciated.
FYI, if some "dirty" language will upset you, please skip this one.
