I would very much like to know this as well. I had both New Adventurer and Buried Treasure available, and was looking forward to buying the buried treasure at the weekend and going to town... but it has now disappeared from the store A friend of mine who also plays has it currently available in their store though (and bought it this morning just in case it disappears for them, too. But it still shows up in their store even now.). Is Buried Treasure time-limited? On a rotation? Or is this a bug or store problem?
