I've been trying to collect meat from all sorts of animals (mostly, sheep / chickens seem to be all I find), and although I can gut them, I can't collect any raw meat. I kill the animal, use the knife to gut, but the body never gives me any further actions beyond 'hide' and 'study'. Looking at the gear screen, I can't find any options to use the hunting knife to collect meat, either. So... How exactly do you get meat from the carcass? I have the feeling I've missed something huge.
