I'm not surr but i guess this could be in the database of the server ? Maybe the Gameobject Table..Not sure but its just a guess
I tried something with game object (ID 3736 - Copper vein). I looked at open (data_0) ID and it linked me to lock.dbc (ID 38). So i looked at column 18 and I also edited it... but... nothing changed.Could you exactly tell me, where is it?
