Can somebody post the raws of the dwarves so they heals things like nerves, please? You know, all those things that normally don't heal which is absolute bullshit.
I could, but I think I added claws to my default one, I don't know if they're there normally or not, and I remember having issues with them. To do it yourself(and I like the idea of people learning to mod), you need to open up tissue_template_default.txt and add [HEALING_RATE:100] to whatever you feel needs improvement. Nerves and brains seem like the big ones, but you might want to improve nails too, just so they don't stay permanently broken. 100 is the healing rate of skin and most organs, but bones heal at 1000, and I'm not sure where you want this to fall at anyway. Lower is faster. I'd personally stick them at 1000 or higher, so that they take even longer to heal than broken bones, but I don't know how quickly nerves heal. This way though, you have control over it.
Horns, hooves, cartilage, all hair(including feathers), nails, claws, talons, teeth, ivory, nerves, and brain tissue don't heal.
Cartilage, nails, nerves, and the brain seem like the big ones for dwarves, since teeth tend to be lost completely rather than breaking, and I doubt healing rate would help that at all.
