Did you ever figure out anything about this issue?

(It sucks that when people who normally answer questions have a question themselves, there's no-one who can answer it for them)

I would not have thought that removing a category from a redirect would do that, but your evidence says otherwise.

Did you try re-adding the category to the redirects to see what happened?
