we were able to fix your dupe with out your help i think we will be fine
stay off our server
just for any others who wish to take advantage of this server (and not be kind to point it out like myself) the other following exploits also work via packet manipulation:
Using any objects "do X" anywhere
clicking of any object in any location (aboslutely 0 position checks)
trading with yourself (another dupe) / Possibly dueling as well as I hadn't had time to check
casting spells on yourself /attackable spells on items for rapid leveling ect.
