That reminds me ... I bought the game for one of my nieces a while back. I sat with her while she started playing. After some time I saw that one villager was nearly a Master Scientist and said that she'd be able to solve a puzzle once she had one.
She excitedly called me over when the villager became a Master, but just then her older sister, annoyed at the computer being monopolised, turned it off at the box. That meant that she lost the past few minutes, including the advance to Master. It seemed to take ages before the game got back to where it was before. I don't think her sister realises how close she came to being murdered.
