World switching

If the store is overstocked or out of stock, or the mine is too busy or mined out for now, you can return to the world select screen and try a different world. The server will make you wait, for about 15 seconds, maybe 20.

You cannot switch worlds if you are under attack - you will either be prevented from logging out, or will die if you do or break the connection.

Some people see world switching as unfair - in a way, it probably is - one thing's for sure, the more people do it, the less useful it becomes.
