I screwed up badly. My dogs have been collecting Tiberium for quite some time now. Because my family had limited resources (I started from broke with an empty lot), I've just been collecting them. Now that money is no longer a problem (and a bunch of my Sims are getting the wish to be worth 1,000,000 simoleons) I cleaned out my rock collection, cutting the gems and smelting the metals. When they came back, I sold them all. I was just thinking, "What happened to the Tiberium spires?" I realized that I had sold them along with the other cut gems and metal ingots. I forgot to let them grow. I had more than 20 of them. OOOOPPPPPPPS!!!!!!!
