I have decided to merge some initial chapters, because their word count was too short, and would make for a smoother read if merged into one. As a result, I now have 83 chapters instead of 85. This is a final change, and no further changes to chapter numbers will be done from now on.

If the book was added to your private library, I don't think this would be a problem, as it'd resume from the last part that has been read.

Nevertheless, it would bother me if I change the numbers with no notice. So I'll leave this here, to clear up confusion and for my own future reference.
