I've download Witcher 3 from gog and changed language to Polish. Gog downloaded the language updates, but settings came back to the English by itself. I've changed it to Polish once again, but strangely the updater started to download Polish package again. i've noticed that after changing settings, it becomes unavailable to change for the time of download. and as a default it's set up to English. What can i do to play the game in my native language?
