Well, I've been mucking about with DF for a little while now, and recently decided to try my hand at adding a new playable race. I've attempted to create a six-armed naga, but if I try them out in fortress mode, it claims that they all have major injuries. I've been messing with stuff for a bit, trying to find out what the problem was, and trying out different things to see if they fix it. I'm sort of stumped right now, and I'm wondering if anyone's willing to give me some pointers on what I may have done wrong.

Note: I added legs and set them to internal in an attempt to see if the lack of legs was the problem. Looks like it wasn't.
