King of Glory Outage and Official Response

On October 8, many players reported that the game "Honor of Kings" displayed the message "Data resource corrupted! You need to restart the game client for resource repair" and caused loss of reputation points.

Players complained that after restarting the game multiple times they still could not enter matches and saw deductions of 5–7 points.

Netizens joked about the situation and demanded compensation.

Officially, the game team responded: "Dear Summoner, we have received feedback about possible data resource corruption during matches. We are locating the issue and will fix it as soon as possible. We apologize for the inconvenience and thank you for your support and understanding."

Later, the official operation team announced that the abnormal issue had been fixed and promised to restore points: "The data resource corruption issue on October 8 has been fixed. Players who encountered the problem can exit and re‑enter the client to resume normal matches. Reputation, rank stars, and peak points deducted due to the issue will be gradually restored within two working days."
