I have a ginormous collection of space rocks. I thought my Sim would break them on the board breaker, but the only space rocks she can break are the ones that show up on the board. Is this normal? Does it improve to the point where I can break my own space rocks? If I can't, what is the purpose of space rocks? I tried transfiguring them and got a large space rock much lower in value than the ones I put on the display. It was a different shape large rock, not the huge, lumpy one you find in the field, but it also could not be put on the board breaker. Should I just sell off my collection?
