This sim was of my sim (that is me) second daughter and youngest child, Vivian. She died in a fire as a child, and nearly two generations later (other daughter's son's wife pregnant) her ghost has not come on the lot. Since then I've moved, and I thought that might alter it, but the ghost of her mother (me again) has arrived in the new house even though dying in the other. I would like to revive her as all her siblings received fulfilling lives and I would like to change that, but she won't ever come. What is the problem here? Is it just bad luck? Is there something I could do?
