I think that for bipedal creatures the despawn could use an overhaul. Killing monsters is very satisfying with good audio que and gore, so there I don't pay as much attention to it. But for the bipedals, sometimes almost in T-pose, they're just sinking slowly into the ground which just looks odd, especially since it happens so often. Since the gore and combat is so satsifying, maybe just add a more cool looking despawn effect, and I wouldn't mind the gore staying a bit longer if it's feasible from an optimization standpoint :)

It is a bug, i think it's a known issue for them but they had more important things to focus on.
