Here's something I've been thinking about ... Would it be plausible to add a sort of "species skeleton" mechanic that the AI could read to NOT give extra limbs or etc to characters and creatures?
It doesn't have to be over the top, could be as simple as a stickman thing that game creators could use to tell the ai what each species has. (might same room for description and loading time.) like there'd be parts like "head, body, arm, hand, leg, wing, animal torso, tail, and etc) that we could "build" to prevent AI from adding things that aren't meant to be there.
(This is both a question and suggestion. I have no idea how this stuff works half the time so this might be completely impossible but i thought it best to ask instead of keeping it to myself.)
