Can someone tell how can i build the prison please ?
Try to save and load the game. For some reasons new improvements are not showing on the list after the first load.
You need about 24 planks and 15 of the item you get for mining in the tavern's basment to build that, also, if you are loading the save from the previous version, save and load it again to update the building list.
I have the same problem, i did that, but the list does not update.
