Wow, I'm so sorry you're having this problem. I've never taken up the Spark'd Challenge. I take it that once you finish creating a Sim in CAS to place into a world, the game doesn't automatically make a copy to you My Library? Yikes, that's just wrong. I do hope another person who has no knowledge on this subject comes along who can help you out. I get dismayed when I create a thread and get reads, but no responses, which is why I said something. At the very least, I hope it gets sorted out.
