Thank you for the fix! My mapping program (Hex-kit) imports your tiles with a very slight offset so rotating them in the program left them out of place.
Loving the new update. Seems like there's an omission; Coast 0724 and 0721 perform the same function, while an inverse counterpart (i.e. land on the lower right hexhalf) does not exist. 0724's grass version (0051) has land where 0724 has water.
