This isn't a bug that affects gameplay too much, but it's absolutely baffling for story continuity: an idol had the wish to center a political single, but as I was producing the single, I got an event with her where she told me she didn't want to center political singles because she didn't want to get involved with controversy. I realise that some kind of system to make sure idol wishes and story events don't contradict is likely not high on the priority list and might be more trouble than it's worth, but getting that particular combo was super bewildering.
