Well that's odd. In the database

MariaDB [angwiki_p]> select rd_namespace, rd_title from page inner join redirect on rd_from = page_id where page_namespace = 0 and page_title = 'Ƿicipǣdia:Nīƿlicu_ƿord_teohhunga';
+--------------+------------------------------------+

+--------------+------------------------------------+

+--------------+------------------------------------+
1 row in set (0.04 sec)

Which is wrong (rd_title should be just Nīwlicu_word_teohhunga and rd_namespace should just be 0). But I would normally assume null edit would fix that.

A probably work around would be to point the link somewhere else, and then revert the edit.

Yeah, it worked.

Thanks.

Leaving bug open for the underlying issue in the software. Its probably a bug that a null edit didn't fix the page

Probable steps to reproduce (Haven't tried):
*Create a redirect to [[Foo:Bar]] (Foo not being a namespace name, Foo:Bar not existing)
*Make Foo an alias for some namespace
*Create Foo:Bar
*Check the link colour of the redirect.

Possible alternative steps to reproduce (which I also haven't tried):
*Create a redirect to [[Foo:Bar]] (Foo not being a namespace name, Foo:Bar being an actual page that exists)
*Make Foo an alias for some namespace
*run namespaceDupes.php or whatever the other one that does the same thing is called
*Check the link colour of the redirect.

Here's a redirect that acts like the other: https://ang.wikipedia.org/wiki/Wikip%C7%A3dia:Wicib%C3%B3ceras

... I won't fix it till everything's been dealt with, if you'd like.
