Is this a bug or evidence of cheating?

Hey. That score is definitely unusual, and I can understand why it raised concerns. If you believe there may have been cheating or an exploit involved, please report the account through the standard reporting path. That will allow the relevant team to review all the details properly and check what happened.

I’m afraid this isn’t something we can investigate or confirm on the forums, but reports submitted through the correct channel will be looked into by the team.
