Fellow Grand Wizards, we've noticed some issues with the leaderboards after the update, and we're very sorry for the trouble!
We're scrambling to find a solution, and some of the current data on the leaderboards will be removed and re-stated once the issue is fixed!
We hope that all you great wizards can give us some time! We will deal with the issue as soon as possible!
Once again, we apologise to all you Great Wizards!
