Is there a way that the Mason could construct things like windows and doors? I see that they can make a tunnel door, but when I like the variety that I can get between Carpenter and Potter. Maybe the blacksmith too? It would be a cool addition
I agree, at the end game the mason barely works.
Meanwhile, we have some good mods that adds more craftings to the game. Take a look at the mod sections, you probably will find something you like.
