Built a grindstone last night, then the crank that you're supposed to use on it, but I couldn't get the damn thing going at all. Put raw ore in the top left slot of the grindstone, then right click on it with the crank in your hand, right? right clicking just opens the damn interface for the grindstone again... :(
So instead we made some stairs down to civilization, being completely devoid of food, we had to do some pig killin...
