No supported translations exists for Finish and Luxembourgish. The migration_lang files for these languages are still in English but one translation key is missing compared to the EA! English original file.
For consistency purpose, the Finish and Luxembourgish migration_lang files have been overwritten by the EA! English original file.
I'm not sure about the translation of 'up' and 'down' method because I am not certain about the context and its meaning. Please re evaluate those translations.
