All my medals and lessons have been deleted since i tried the new russian option
all i can see is the english for russian speakers option and i can't switch languages anymore. please fix this.
Nothing disappears, just in our course interface you can see only the results of the courses for Russian speakers. At least for a while it is so. As soon as you change the interface you can see your other achievements. But yeah, when it happens and you think you lost all your progress, that is shocking :)))
