I've got a feeling that Wikia doesn't really respect the MediaWiki markup as much. Half a year ago, they removed transclusion features for the Special:NewFiles page (that is to say, if you inserted on a given page, you're no longer getting a gallery of the latest uploaded images, but instead a link). This was a feature that was present in all the other MediaWiki-based wikis. So yes, they removed a feature that was supposed to be part of the system they themselves are based on.

When I asked them to put it back via Bug Report, I got the answer it was deliberately removed because... no one uses it? Oh, and from what I heard from the staff member that contacted me back, the development team refuses to put it back.

So yeah Wikia's a mess.
