The current butchering process? highly tedious and takes forever- even with a butcher's knife that has a miniscule chance of actually being your best q cutting tool.
My suggestion is to bin it all, new implementation.
Right click the dead animal and select a single option - Butcher. You walk up to the animal and go through a short timer and animation of lopping the beast up as it goes through the stages of processing. After this, it suddenly converts into a new object- a Butcher Pile. The butcher pile contains all of the products from processing the animal- Meat, Intestines, Bones, Etc all stacked up on top of the hide. Items within a butcher pile won't despawn and you can pull things out in chunks, making the process of butchering a ton of carcasses far less annoying and the process of putting everything away after less of a hassle that won't require so much constant back and forth between storage containers.
