No wood, anywhere.
Wheat fields unfarmable.
Swords can't be crafted.
Heavy Armor can't be crafted. ((So far as I can tell, I've tried combinations of Lin, Iron and Leather, of various shapes and sizes.))
I've had an issue where, after taking up a class, I'm reset to where I logged in last. I've mostly lost money and equipment to it.
