As the title says, Achievements on Steam changed to Italian, even though two days ago were in English. I didn't change anything, and English is my default language in Steam. There is a thread on Steam forum too, but noone knows how to put them back in English.
Same here. The page in question : http://steamcommunity.com/app/233250/discussions/0/619568192767135147/
Mentioned this in the build thread an hour ago, I confirm this is a thing I really wonder how this happend.
