I've had to rename a few because I dress the doctors in "green scrubs" and the Elders in white. It gets confusing when they have the same name and look alike. A couple of times I've renamed some villagers...lets just say a very bad name, like one female who, while there was no food in the bin and she was a farmer, decided to go to the love shack. Yep, I was very angry when I had to constantly scan the grounds for mushrooms. I also renamed the daughter who was, I'm sorry to say, stupid.
