[Source] On the last day of January, the servers for Dragon Nest Europe, published by Shanda Games, went down due to a technical error. It went back on after a few days, and players were told a huge chunk of data has been lost, including titles, achievements, cash items, and more. The official reason given was “serious technical failure”, though some folks claim the game might have been hacked.
Though Shanda Games will offer compensation, it remains to be seen how much data can be recovered, since most are lost. I doubt players are going to be happy with any form of alternate compensation. It seems rare these days to hear of such wide-scale loss of player data, perhaps Shanda Games should investigate further. There is a Reddit chat with players ranting about the situation.
