Dupe/Rollback method for Wonderland Online

I’d like to get a method to dupe/duplicate items in new wonderland online (hk). All previous methods were related to WPE PRO. all previous method are patched and not working anymore.. the game is old and i think it's easy for you to find Dupe. there are 77x errors in the game ---> [login to view URL] i can show you all the glitchs and errors i have found but im looking for a method that can crash the servers to get rollback or find a way to get rollback and dupe or duplicate item. there was a method before but it's patched now, you record the packet when you delete your character and then send it when you are in the game, you get error:15 then you will get rollback and dupe [login to view URL] the game has 4 time maintenance per week and sometimes maintenance also cause rollback and dupe so im looking for a serious person who can help me with this! thank you!
