I thought supplemental was for pages not there anymore - not pages removed from the navigation array - but there you go - you learn something new every day.
i must have inadvertantly stopped Googlebot from accessig this page somehow and it's just guessing it's gone because no external site links to it.
Did you redevlop the navigation at any point?
Three or so months ago I noticed my software was serving directory index pages in three possible variants (/directory, /directory/ and /directory/index.html) so I modified it to serve /directory/index.html as the default and 301 redirect the other variants. However I don't believe this is the problem; Google seems to have caught up with the changes during the last PR update, and a directory with a strong external link to example.com/directory/ shows PR for example.com/directory/index.html, while a similar directory with no external links shows no PR.
