Ya, the only draw back to this challenge was needing to use the kaching cheat. I had to look up how to use cheats, now I know how to cheat!
I also finally tried the Moodlet Manager while testing some advanced ideas. Now I understand why it is banned, though this challenge is not long enough to earn the LTH points for it.
I don't think lovergirl cheated. She may have made the same mistake Metro made, and missed a location. Or, just a strategy that I have not found yet. Hmm, both lovergirl and I have finished, I will PM her (can't divulge my strategies here any more then she can!)
