I think, the reason why HK servers getting this event late is because they time is based on NY region, which is 12hrs earlier th* here in HK .. Makes sense since 5am is the Server Reset, and we got the event 5pm here in HK ..

Let's just relax, they know the drill :D ..

EDIT : The keys just came :D

As long as this event have Mood Scrolls and Myoboku Gifts, this is one of the greatest F2P event :D .. Got some of my Treasure Super Rare Ninjas to 65% Mood ..
