2.1 Patch Notes
Treasure Hunt has been added.
In the course of gathering, Disciples of the Land will now be able to obtain items known as timeworn maps. These maps can then be used to reveal the location of hidden treasures.

* Upon obtaining a timeworn map, players will be unable to find another for 18 hours (Earth time).
There has never been a time where you could gather maps back to back. If there was, you must have crossed over to another reality.
