This is a simple quality of life mod, which disables the mental break called "slaughterer". For me, animal husbandry is a lot of work, and I care about the animals I've trained, so I don't want anyone to slaughter them before I manage to get another pawn to stop them.
It changes the core files, so it won't be compatible with other mods that spesifically changes the slaughterer, not that I can think of any mods that do.
Update 1.1: Small fix for linux users.
Oops, I saw my spelling error on the picture.
