It appears analyseChapter() is not being called at all, or the value of chapterText is being ignored. Tested by bypassing story parsing and just assigning a string to chapterText.

Poor testing... the actual issue was the lack of author's notes. There was no error handling if the RegEx failed to match, so the function exited early. Adding error handling to RegEx matches will hopefully prevent further issue.
