From Site Conquer Online,
Regarding to event Anniversary PK Month, we have received a lot of reports from players about other plays using bugs to get extra PK Points in Ultimate Fighter, which seriously damaged the fairness of the event. Hence, we decide that Points will be counted only during 19:30 to 19:50. We will release the correct PK Points and Rank as soon as possible.
Thank you for your kind patience and understanding.
