This is the Happy Wars Management Team.
Thank you for playing Happy Wars.
We are aware that the Special Challenge that occurred between August 12th and August 15th (UTC) had an issue where players were unable to receive boss rewards despite damaging the boss.
We are currently examining the origin of this issue. We will post any updates here on the main site as soon as they become available.
We apologize for any inconvenience caused.
We look forward to seeing you in Happy Wars again soon.
