Hi there, Language switching has been fixed, all languages are available and switching correctly. Sorry for anyone who has been affected by this issue. We also have reports of a few people losing save data regarding puzzle stats. I have not been able to recreate the bug but do not stress, while it is annoying this will have no negative affect on gameplay and should I be able to hunt down the source and fix it, running the puzzle again will restore the existing data. OLD POST: Hi there, We have noticed an error with languages not appearing. We have repaired most, however Brazilian Portuguese and Russian are experiencing some issues. We will fix these as soon as humanly possible, thank you for your patience
