MM2 Duping?

So Anyone know any duping methods i know of this old one if it still works can someone let me know?

Requirements:

A player with a knife you want to dupe (player1)
A player who you will send the dupes to (player2)
Windows 10 edition of ROBLOX
2 things to play ROBLOX on

So! Here are the steps.

1) Player2 sends a trade to player1.
2) Player1 puts in the item(s) they want to dupe in
3) Player1 accepts.
4) Player1 goes to windows 10 edition and logs in as player1.
5) On windows 10 edition, press play on mm2
6) As soon as it says "Joining server" on the loading screen, Player2 presses accept.

You should now have duped your weapon(s)!

nice i'll give this a go
