I wanted to change my game's language to English and so I've made the client download the data pack.
Now, testing it.. :\ Only the launcher is in english now, the game is not and even worse the languages dropdown is now empty, and I can't do nothing.
The only thing that worked for now is launching Diablo 3 from the "Run" command adding a line that forced the Locale "EnGB".
Do you guys know anything about this?
