All Bull characters starts with lots of negative value, mostly ok, but -400 robotic will make the Bull maim or kill player's character.

Reproduce:
Give the bull a skeleton repair kit
Damage a robot character or character with prosthetic limb (get in a fight somehow or edit value)
Command the bull to repair the damaged character



I've 'fixed' this by editing the Bull robot stats from -400 to 1, unbalanced but won't kill my own people at least.
