There is nothing challenging in night, it is just simply annoying... I didn't notice it affects the game in any other way than forcing me to use torch (that, btw, doesn't give much). Yes, please, remove night or make it affect somehow the gameplay (nocturnal behaviors for animals etc)
I don't like the weather as well, but I can see my guests and animals don't like it either, so I can see where the challenge lies in this feature
