Because of how people have massively abused the system of generating Heartstone/Booty Chests in previous Valentine's Weeks, which leads to huge strain on our servers (as individual players create thousands of worlds each, just to completely discard them a week later), we are changing the method of earning rewards for this Valentine's Week.

I won't give away how it works, but I want to be clear about one thing: it will be based on sharing love with other players, which is what Valentine's is about, so having lots of empty worlds will not help you! Don't lock worlds for Valentine's! Tell your friends too.
