I really missing some things that i´d like to see either as craftable furniture or , well yes you can put some of that in the list for crowns
for the guys that own a castle i think they would like to put a small boltthrower (aka ballista)
on their walls, and a round targeting practice
for bow in the yard. Some fighters guild areas have these.
Weapons and Armor racks
would be nice too, and the occasional decorative Shield, Axe, Greatsword
Then there is also the dire need of hay, strewn and in a pile
for the stable area.
For the lovers of undercroft design, i recommend spiderwebs, pile of rubble, pile of dust
, oh and a tapestry - torn
not to forget
Household animals, like chicken, pig, rat, goat
, but thats maybe a thing for additional npc´s that can be placed in the housing area.
feel free to add your ideas
have a nice day
