The recently added High Norwegian language is incorrectly named in the language menu. It says High Norwegian (landsmål). Landsmål is actually the name of nynorsk, which already exists as a language in the game, so there appears to have been a mixup. The proper name for High Norwegian would be Høgnorsk.
