IAHGames has updated Singapore servers to v23.97.53 (Armonia Episodes 4+5). The new event is basically 2015 Elation Event, already implemented previously for Korean and European servers during Lunar New Year.
Frankly, this is TERRIBLE! They did not even have the Upgrade Your Gears! event, which sells Enhancement Boosters and Imperviums at a discount, giving players a last shot before converting to the new bloody system. Both European and Korean servers had the discount event just before Episode 5 update.
This leaves American server lagging behind at Episode 3... I hope T3Fun is not going to do the same by skipping straight to Episode 5 and bypassing the discount event. But given their service so far in the past few months...
