I think there was only one reference to that, in the slang entry for Weaving the Basket. I just edited that entry and changed it to Kubb.
Keeping terms clear is also why the Planet Kubb Wiki seperated the official Glossary from the Slang entries. They are not mingled together anymore.
A search for "knight" now yields no results on the wiki.
