I know, this might be updated already because of its age..But just incase it isn't and I've been dying to know for almost 4 years now.. What is the mithril coin bug or how does it work?
For example, I had a friend i met in RO and he was doing it for me but wouldn't explain it. He'd exchange zeny to bronze coin or whichever coin he wanted, and then Mails it to me. Somehow I get a lot more in my mail, and he only made one of the coins. I have a feeling that this is a bug or exploit and is not needed for WpE. Can someone please help me out, thanks!
