The maintenance was a success and the game is back ON.
The dev has managed to make some changes in order to prevent further offenses as the ones we've been experiencing for the last few days. We had to add some more trade restrictions: Coins of Edrendros are no longer tradable and you won't be able to buy 1000 bonus points with merit points to the NPCs in the three kingdoms.
This should be enough for the time being.
Besides, I'd like to announce that all those who had accepted great quantities of gold from yesterday's hacker are already banned.
Sorry for all the inconveniences.
