Mayhap I missed something but is it supposed to translate ruskie runestones as well? Doesn't for me.
Just spawned a testalt at a guessed HS and found a runestone cuz I wanted to see this transla-thingie in action, imo it's funny as hell. But it is russian and stays russian, even tho it's ticked in the options.
In Soviet Russia, universal language adapts to YOU!
