I was looking something up and all of a sudden, URL error codes are being vomited out the page's mouth. I bet it's because of that MediaWiki update, but that's just me.
(Plus, Rofl, if you're reading this, you knew how you told me to use this to report wiki problems from now on? Well, here you go)
EDIT: The only thing that works is the "Go" Button which sends me to an existing Wiki page, but that is literally it.
