I found it. Can you please check the link to Theakinetics from the glossary page. That one shouldn't be broken, though I can see the one from "bishop" definitely is.
I'm not sure why you can't at least to get to it from the glossary page itself. The only instance of wiki_theakinetics (the wrong name) that I could find was in the link on the bishop page!
I'll have to push out a patch at some point.
