Anti-Dupe Script

Role this script in QA (Query Analizer]
This script delets all the items with the same serial!

How do you test it:
1.Be sore that you role this script in the DataBase MuOnline!
2.Open MuEditor
3.Select your account
4.Open your vault and add an iteme (for example Broze armor) with the serial 22222222
5.Close the vault and be sore that you save it
6.Open an carracter inventory and pun an Bronze armor with the same serial!
7.Save invetory
8.Enter the game with your account and open the vault ... SURPRISE! No Bronze armor
