I was on a date, with the "friendly actory" from the beginning of the game. His hair randomally changed, after I turned my tablet off and back on. Didn't think much of it.. except that it looked better ;p. Then it changed back the next time I turned it off, which was depressing.
Has this ever happened to the people in your game? Just wondering
Another thing, I've noticed that the rivals hair is usually different.. What do your 'friendly actors ' look like? Post pictures!
