Issue description for reward game update on the evening of November 11

To all bounty game players:

After the opening of Bounty Game on the evening of November 11, UE4 reported an error due to the server failure of the new version, and then it will go back to the previous version. With all the staff of the studio, we sincerely apologize to all the players for this. Now we know this problem and are repairing it in time. The service opening time will be notified later.
