Beginning with v184.108.40.206 (the next hotfix patch), there is a new entry to the language.def file that is required to allow translations to work with the game.
This has been added because old translations have been causing issues with quest progress for some players. Users with old translations will now be forced into English, and be given an error message requesting they download the latest version of the appropriate translation.
It’s important that only up-to-date translations are uploaded to the localization portal, and not any work in progress stuff.
