Some time ago one guy told me that he know "how to get money for free". I thought he lied. But no... There was a bug. You can buy pickaxes, sell them for xp, buy bulldogs in npc and sell them for money. In this way you can earn money for free. A lot of people used this method and now they have a lot of money, items and nice rank... But what with other players? Nothing. Any penalty? No... Just fixed a bug (thankfully)...
I can't play with thinking that some people can play with impunity, with a lot of money and it is certain that they will kill a lot of people with items from this money
