I don't see anything in the mod file about removing carnivore lizards. Are you sure they're in the vanilla version? Yeah, Raise Skeletons/Dead has had the fatigue increased. It's nothing like the nerfhammer that Relief got after the devs were shown the rather abusive skellyspam strategy.
ah no, the carnivores are gone from the vanilla version too, thats not from the CB
Raise skeletons got higher fatigue, and the longdead from reanimation and that spell got rusty weapons and armor and is generally weaker.
