There shouldn't be any of such conditions.

I fixed it. Footnote references should be allowed there.

`org-footnote-auto-adjust' still does its job when, for example, a new
footnote is created or a footnote is deleted. It is fragile when
copy-pasting a footnote reference across some text.

Anyway, it should be possible to fix most of these "black holes", if
only we are aware of them.

Thanks for your report.
