The only ones I made living again where the Goths in Moonlight Falls and there are a couple others I can't remember.

Thank you

Do you got a link to those books I can't find them

It seems I made mistake with the babies when I loaded up my game they had the same map tag color as their parents guess the tag was just late on updating

You have to have the Kama Simtra add on installed which I'm assuming you already have

Once they get their first skill point in the KS skill you go to a computer and Register as a Professional.
You'll still have to have your sims find customers as the mod won't bring them to you

I'll have to play around with simbots never really played those either didn't know you could do that with them

I haven't really played with plumbots and I'm not sure how many trait chips slots they get but I would improve their quality to the needed level I believe it's 8 and give them the Limitless Learning chip if I wanted them to learn the skill through experience.

Since the KS skill is a custom skill you would probably have to use MC to raise that way as I don't think a tuning mod would work in this case
But that's assuming they can even have the skill given to them by MC

Your welcome I usually make them living sims again I have a sim I keep in the Bin for just such purposes
