Very unexpectedly came across a colonist butchering a Sightstealer for organs. My sick fascination kicked in and had to watch - shame they're just normal organs. Seemed to bug out though... kept retrying with just shoulders, pelvis, torso (though "0 HP"), right lung and spine still in place. Would put away and then retry repeatedly.
One of those things you pan past, then return back "... huh." Intended or emergent?
