Thread:Translating talk:Wikia/Special:CreateNewWiki: ia (Interlingua) is missing from "All languages"

On http://www.wikia.com/Special:CreateNewWiki (page for creating a new wiki), when changing the language of the wiki to be created, ia (Interlingua) is missing from "All languages", even though a translation in ia has existed for some time (even see http://www.wikia.com/Special:CreateNewWiki?uselang=ia). Please add ia to the list. Thanks.
