@Karritz I'm not having them live in Oasis Landing just so they can do those careers. I tend to send my sims to vacation worlds or OL to get a break from whatever they're doing in their homeworld, and especially to have some time away from their entire household, where things can get a little overwhelming (or sometimes a lot overwhelming). For this household of 4 humans, 4 horses, a dog, and a cat, I need a break from the humans having to spend several sim hours every morning brushing pets, cleaning horses' hooves, and multiple affectionate interactions, and play only the humans for awhile. The plan to have them join the ITF careers is secondary, but I've always wanted to have a household live there for several sim weeks and do the careers, maybe even raise their children there, along with everything else they can only do there. Just so I can do it at least once.
@mw1525 Thank you. I just didn't want to risk messing up their careers at home. The nectar maker is at level 10 in his career, due to keeping nectar around until it appreciates to a value of several thousand simoleons per bottle, but the sculptor only makes and sells one sculpture a week, because she's working on mastering all the skills and making the skill challenges. So I don't want to lose her career progress. She's the one who will do the bot building. I know she can do it regardless of whether she registers, but I'd also like to go through the career at least once before the time comes that I can't play the game anymore, which I hope will not happen in my lifetime, though I suspect it's not nearly as far away as my own likely expiration date.
