Unfortunately I can't think of an easy solution to this problem, but if I recall correctly, other people have been reporting similar issues over on the Steam forums. You'll probably have more luck searching/asking there.
We'll consider adding language links to the front page once the wiki activity and amount of translated pages get to a high enough level. Alternatively; we could make translated subpages for existing articles. For example: the translated page for Satsuma could be Satsuma/de, which would be linked to from the original page.
