Something new and funny in experimental B-8341

so i’ve just downloaded and tried latest experimental build and i found something new and funny when i killing undeads.

so when they got gibbed, they no longer drop into bunch of meats everywhere but instead drop something called “butchery refuse” that can be eaten and has no effect at all, and tainted fat and bones in big amount (last seen was 106).

is there new plan for gibbing mechanic?
