In dwarf fortress (latest version 27/03/2019) all the possessed dwarfs that I have had have failed to collect the bones that they require and instead go insane. I'm new to dwarf fortress.
I have tried looking online but other peoples who's issues were usually fixed haven't worked for me. I have also tried deleting the refuse stockpile (outside but close enough to my craft shop (the shop that my dwarf claimed)), moving it closer, butchering new animals, and letting my butcher get clogged up. I honestly have no idea. My assumption is that either I've toggled something in the game that I shouldn't have or this is a bug. Thanks.
