I was editing a chapter for release and noticed that the contents of a footnote - footnote eleven - were being placed outside the footnote when I read the preview chapter; the footnote still existed, but it was empty, and what was inside it was placed after it. I repeatedly tried to make several minor edits, but nothing was achieved. In the end, I decided to see if making a new footnote eleven would do anything. The contents of the new footnote eleven were placed outside, while the contents of the previous footnote eleven remained within the footnote. Is this a bug?
