A pet buff issue was identified earlier today, which allowed an avatar to receive an unintended attack speed buff beyond the normal buff limits.
This issue has been corrected in a server hotfix that was implemented during the past two hours.
Our team was able to identify a small number of Summer Mayhem participants who had this unintended buff active, and their Summer Mayhem scores have been reset. This affected only a small number of avatars: 5 participants in Summer Mayhem Annihilation, and 7 participants in Summer Mayhem Assault.
We appreciate your patience during the unexpected downtime caused by this issue.
