We will be having our May 2021 game maintenance this Friday, May 7th, 2021 @ 6:00 a.m. website time. It will take about 3 hours or so. April event will end but reward exchange NPC (GM_Wan in Mega Square) will remain for another month to enable players to exchange for rewards.
Special boxes/wings/hats/pets offered in April will be unavailable about 1 hour before maintenance starts. So if you want to get anything from there, please do so before that.
Hint for May event: cards
