Since the release of 0.53 I have been unable to quarter anything. pig,deer,cow,rabbit,people, yet to find a sheep so not sure on that one. But i've tried standing, crouched and prone. i've tried different types of knives and still nothing. aside from that. i've also tried fishing for the first time. it was fun. my friend was on eage thinking we were going to get shot. After i got a fish and turned it into filets. We made a campfire attached the cooking tripod and cooking pot to it and after about 5 minites of waiting the filets still were not cooked. so i'm not sure if it's a glitch or if theres a different way to cook them. I looked on youtube and looked up guides on it and the way i was doing it seemed to be right.
