I'm sorry to announce you that the leaderboard got someway wiped out, luckily I found a fix so with this little patch you just have to log in the game menu and it should be hopefully re-uploaded.
Don't worry about rank not getting updated, you just have to refresh after the first time.
To apologize I can say that a big patch is being prepared for STAY's anniversary, it will include several bugfixes and new content. Don't want to spoiler so please hold on and wait for its release.
Thanks a lot to all the committed players and I apologize for the inconvenient.
