Hello, I'm not sure where I should ask this but I came across a strange problem that needs fixing; I can't create a new page titled "Detroit: Become Human" because the colon causes an automatic redirect to another wiki called "Motor City". It also creates a page titled "Become Human" and won't allow a rename for the following reason: "This page is not movable.", although I'm admin of the Fahrenheit wiki.
The Fahrenheit wiki and Heavy Rain wiki has encountered this problem when trying to create the page.
It seems you have stumbles across one of Wikia's "hidden" interwiki prefixes. That being said, there seems to be something off with the way interwiki links are being handled at the moment. It might just be temporary. Unless the page is time sensitive, I say give it a work day (not weekend) or two and see if the problem is resolved.
