I'm thinking that one way to get an unlimited supply of gold would be to tell the server that you've dropped 500 gold wihtout actually decreasing that amount from your stash. But would this really work? From what I understand the server does calculations and if they don't add up you get disconnected. So if the server sees that you've picked up 500 gold and also sees that that 500 gold didn't decrease from your stash then there may be an out of sync error. Am I right?
