I'm have an idea. During the game there is a message in the chat: "A Mysterybag with ... $ and ... points is spotted somewhere in ...". And we need to find this misterybag. When you find it, you will receive a reward, written in the task. The ability to search will be available in time say 15-30 minutes. I think it will be interesting. To begin your search, you must write a command /mb for example. Next, the players, who wrote this command teleported to the top of the mountain Chilliad (to be honest it was) and start searching. Command /mb during the search, you can write as often as possible to find the distance to mysterybag.
