The past few days have been busy with many players sharing the issues related to this exploit and your feedback/information has helped us release the patch that we have today.
We will continue to monitor behavior, leaderboards and messages here to ensure that all is good with this recent hotfix. We appreciate your patience and feedback on the matter. Thank you.
