A quick rundown on the zombies:
The Zombies essentially just Walking Corpses, nothing more special to them than that
They are 100% obedient, and have limited intelligence (about the same as something like a moderately well-trained primate, but without emotions)
They do not require resources of any kind
Almost all of the zombies that are running around are from the city's own graveyard
The zombies are used as slaves would be, such as for mining, construction, even domestic servitude in some cases
Long story short, this fantasy world is full of kindlykind necromancers who felt like all those dead bodies arewere going to wastebe wasted just sitting in those graves and not helping anyone.
So now it's a common occurrence for every city to have it'sits own personal Necromancer, who simply revives the corpses of anyanybody who diedied within or near the city limits and puts their corpsethem to work for the good of the people.
Obviously having a bunch of walking corpses shambling around dropping pieces of their limbs everywhere is going to present some issues, like for instance the smell.
So my question is: what issues do these Zombie Servants cause, and how can I mitigate them using late-medieval technology?
I'm okay with advancing technology that is needed a little bit (like for example developments in deodorant technology) if it is a technology that this world would have an increased reason to develop due to the zombies.
