Direct answer: Netmarble says it identified cases involving the use of abnormal methods to shorten clear times during Leaderboard Regular Season 3 and issued an official notice about the problem.
What is confirmed?
The notice confirms an integrity issue affecting the season's clear-time context. It does not by itself confirm a particular player's result, exploit method, compensation amount, or final ranking outcome.
How should players read the rankings?
Keep the official notice as the reference point and avoid treating suspicious times or community explanations as confirmed facts. Check for later updates before making a claim about rewards or resets.
