Hello, this is not a bug.
We usually create provisional profiles for all CRL participants, so that results can be displayed while the event is ongoing.
Now that this edition of CRL has concluded, we are removing these provisional profiles. Only approved profiles will remain active and display CRL results.
But Why is my account ranking deleted while other players who are not in the top1k are still there?
Again, you just had a provisional profile.
Players who have permanent profiles keep it.
