In Legion of Heroes, three times per day there is a "Hot Time Event". As far as I can tell, this consists of a message to your inbox with a gift (or two) attached. There is a tab on the right hand side titled "Events".
The hot time events do not appear here. But they are called "events". What constitutes an event, and has there ever been one?
I know that the Korean version of the game is much more mature, but I don't speak Korean and couldn't understand the google translate of their sites.
