If the cause of this problem are the players who are doing dupe of item, then I myself am afraid for the future of this server. As I remember, when doing dupe in PH they are waiting for maintenance (Old School Dupe). But here is different. Those player are the one handling the stability of mandara which is I am afraid so. Why? Because they can dupe anytime they want using roll back in mandara. GM need to edit the encrypted code in mandara and other maps which is specially because our server's file came from the other server.
