Thanks everyone, I can't stop staring at them
As soon as Carl start accepting uploads for Swap Shop, I'll sent it to him (maybe a Small park with a chest filled with these goodies?). With Leto's cloning trick there can be as many copies as you wish. Perfect decoration for casual games.
I used 2 Sims, gardener/sculptor made perfect garden (also waiting for upload, with 45 perfect omniplant seeds in a chest
) while other break boards and did transfiguration. Since I played in small world I'm testing for Simstar, loading time was crazy fast, so it wasn't too hard. Plus, my martial artist never got a single gnome, so sending gems to be cut was without a single loss.
