I thought you can get more than 1 since its a pack but nvm

Expectation vs. reality hahaha

If anything, just make it a treasure map, they've given us stuff like small stamina potions. But if they were to keep it, then yeah, give it more then 1 treasure map, it's not really a pack, and more of a wrapping, otherwise.

This have to do with how the treasure map works. In reality, treasure map in each zone is actually a different object. This is proven via black market, when it is available to buy. You will see that the amount you own is a tiny number even if you have a lot. Giving it directly would require randomization on the giving part so it will require a longer reward list. But giving it in a pack, they can offload the random to the pack and make it easier to handle.
