My sim needs to find a pink diamond for his "ultimate invention," a simbot. He's already delivered the plutonium and life fruit. I've been checking in map view every day for a whole sim week, so far, and sending him to the consignment shop to look for one, but so far, there haven't been any. The icon will show up in map view, just like all the other collectibles someone has an opportunity to collect and deliver, won't it? I had another inventor a long time ago who made a simbot, but I don't remember it taking so long to get the pink diamond. Is there any way to increase the chances of him getting one?
