is apparently broken for non-English cross-wiki imports. (Admin_Forum:Scripts_not_loaded)

This doesn't work:

But this does:

The cross-wiki prefix is apparently not actually an interwiki link, it's really just the name of the database that holds the Wiki content on Wikia's servers (it.onepiece.wikia.com is stored in a database called 'itonepiece', not 'it.onepiece' so that's why the first fails but the second works &mdash; an interesting part of this is that it doesn't generate a failure call to   like it does for non-existent pages on a real wiki, you just get an empty script response). None of this is explained or documented.

Also,  seems to work everywhere except on the dev wikia itself. This is a minor problem but it does make it more difficult to use  in   since you have to explicitly check for that and implement a fallback loader.
