I just finished a new release.
I encountered a passage in the book that doesn't quite make sense. Just a single sentence that is out of place. Grammatically it is fine, but in context it doesn't seem like it fits there.
I believe it may be a left-over from when a draft was being revised. The extra detail would have fit in to a slightly different piece of plot than is in the book. It feels like it is a left-over reference to that plot point that was not edited out, when the rest was replaced.
Can I/Should I contact the author/publisher and ask if that section is meant to be there? Perhaps I should post on their forum and ask about it.
If this was software I would file a bug report. Fiction books don't have bug reports. Though I have seen them for nonfiction.
