Dragonica EU Duping Exploit

[Pikaone]

Hi.
I'm playing a game called Dragonica EU.
Some people found an exploit to duplicate items (only stackable).
I would like know that because the game become impossible because these people commands the economy of the whole game. And onestly i don't like it.
I want to learn how to dupe too, because well first of all I will farm much faster and I can pvp the people with 20+ gear and maybe win. I've asked a few people about how to dupe, they've talked to can't dupe though they haven't test but anyway, they say that it's very EASY to duplicate items on Dragonica.
I tried to start the game in Sandboxie mode and then use Cheat Engine. It works but when i move / trade / use / interact with the stackable "duped" item it turns back on the previous, real, number.

I think that there are many methods to dupe, so if you know one method / exploit OF ANOTHER MMORPG TOO just tell me because in Dragonica maybe there are the same bugs, then the same method can be applied on Dragonica too. I'm saying this because i think that maybe there's just a bug that allow you to dupe in game without scripts like Cheat Engine.
On Dragonica there are many things that i think that can help for dupe: Vault, Guild Vault, Trade with others, Mailable items, personal market.
If anyone don't want to reply me here can do it by sending me a pm.

Thanks. And sorry for the bad english.
