I'll have to look into that - on pages where this occurred, did you edit the pages? it's possible that on the new edit of the page, the API "corrects" links to their new location.

This also leads to the question of how the redirects ended up 'unused'.
Yes, you can manually force a page to become a redirect page by putting in the editor:
My most direct problem now is that someone published a link to people outside, and that link now fails miserably. Is there a way to manually insert a redirect into the system, without hacking the back end too heavily?
