I ve been putting a 100h in a modded save in which I had no mods that altered animal drops. For some reason it s been like 30h since I last got any drop from an animal, even though I killed wolves, bears, boars, rabbits and whatever else I could find. I can harvest them, but the corpse contains no drops and does not turn into bones when closing its empty inventory. So I can no longer acquire pelts, meat and fat and it s starting to be a problem in my save. If anyone has any idea on what could go wrong, I can give more detail if necessary but I d really like not to lose that save after all my time spent on it. Edit : I am a dumbass and forgot to mention the version being 1.21.1
