There's a bug in the new wiki creation script which allows zh-tw, zh-cn, nn, and perhaps other language codes which are defined but had been intended as aliases to be automatically created as separate wikis. Such accidentally created wikis are not supported and may get closed down when noticed and someone gets around to backing up their content.
I've altered it now so that languages have to be listed in both langlist and languages/Names.php before they can be created. So this sort of thing shouldn't happen anymore.
