Suggestion to help with recent key duping issues

[talonexstar]

Hi there! So, recently, key duping problems have risen and I don't see them stopping anytime soon. A proposal I have(bear in mind, it comes with its own hassles) is to change mystic keys to become unstackable. If this were the case(example: any unstackable item), duping mystics would become much less viable/probable. The hassle that comes with it(maybe minor) is that every mystic key currently on the server would need to be converted(if it wasn't duped, of course). Anyways, maybe this could help.
