Yeah, unfortunately the real cache is not located at the posted coordinates.
Recently, I've been falling back into cipher land which has given me a few ideas worthy of a sequel to the original Theoretically Uncrackable!
So here goes nothing, if you've solved the original puzzle you'll have a headstart, if not, I suggest starting there! Even if you've cracked the OG, it might prove helpful to revisit the past!
The coordinates to the cache, as well as a few extra tidbits, can be found in the message below:

Thanks to Samuel737 for gifting this container! :D
Take care at GZ, it's a bit of a challenge!
