If my telepathy proc was correct, you're complaining about specific sliders set to extremities resulting in relevant body parts becoming insanely stretched, inadequately angled and/or otherwise looking more like graphic artifact rather than a body part.
Game version 0.641 is EXTREMELY picky about specific sliders' values.
Don't set slider values in NPC/enemy configs to above 1 maybe. For some, 1.2 (and 1.5 seldom) might work fine too.
(upd. Sheesh... Now I remember why I've dropped this game in the first place... I grew too damn tired cherry-picking then fixing slider values in outdated mods...)
