Bad leg trait/Canes?

[Cropsey]

My only issue would be the surgery replacing the leg. There's always artifact limbs that could accidentally replace the leg, in which case how can you tell which leg is the "bad leg" just by looking at it? I'd rather have it stick around if you replace your legs, but it just transitions to pain in your hips or your back, or how the new leg(s) just aren't fitting right.

Interesting point.

It would be easy to have it show up under the examine command, something about a replacement limb not looking right. However, that's a little eclectic for a surgeon doing it and I know if it wasn't immediately obvious, I'd go insane. There are, as far as I can think of, three ways to replace a leg. An art, sewing someone else's leg on (ignoring how you obtained the spare leg) or robotics working  their magic.

An art limb could be as simple as a message in chat saying something along the lines of "but something still doesn't feel quite right" and you keep the limp (for some reason I've always envisioned them as transmuting flesh to something else, but maybe that's just me).

Surgery is a different kettle of fish to save the sanity of the surgeon. I think the best way to do it would be two messages, one to the person with the leg, similar to above, you keep the limp. To avoid the surgeon trying again and again or thinking they messed up, something about "you've done the best you can" (hopefully a little more fleshed out, my brain does not word too well) could clear it up, and the limp is kept.

The only way to totally deal with it would be treads, or being borged. As for cloning, I don't think that could justifiably keep the trait, same as the stumped trait (but maybe a fun one for a random-roll cloner defect)
