Some time ago, my sculptor made an Immoderate Water Fountain in ice:
It's a working water fountain, and I'd like her to make more of them, but for some reason it doesn't come up as one of the options where I can choose what I want her to make. I thought once a sim had made a particular object, they could always replicate it. Do sims forget how to make things? Is there any way to get this back as a sculpting option? She hasn't made anything new in a long time, even when I just tell her to "sculpt", without saying what. It's rather sad if this is the only one she'll ever make. If she had to forget something, I wish it had been that stupid freezer bunny thing!
