I see people duplicating items and that ends the game, I'll try to explain how they do it.
1- They place the items they wish to duplicate in a backpack.
2 - on a certain server leave it on the ground.
3- A friend sends an invitation to another server in the same region.
4- It returns to the initial server and the backpack will be in the hand, while the other on the ground.
