I have contacted you twice, and since the new version was launched with unstable servers, the problem of Trouble Saving Earned Rewards From Mastery Mission still exists, and I am unable to receive rewards from the new event challenges. As a fully collected player, I feel very troubled. This bug has been bothering me for more than half a month, and now it has affected the acquisition of new event collection items, I hope you can contact technical personnel as soon as possible to resolve the issue. Do not suggest logging in again, restarting the game, or reinstalling the game. These methods are completely ineffective. I hope your technical personnel can check the server data of my account and make them correct as soon as possible.
