an unofficial user-made patch (version 1.10 as of february 2013) was made available in september 2011. the patch addresses issues with broken quests, fixes spelling and grammar errors, adds proper english localizations, adds english translations for over 1,000 quests which only had description text in the german version, and fixes countless other issues. the patch is created in such a way that the game will not detect modding and therefore fully allow unlocking achievements. the patch can be installed and uninstalled at will since it does not affect saved games.
