How is your game running with Seasons?

It's been okay so far except for one incident of a Sim just freezing in place no matter what I tried to have him do. It was a change from him constantly wanting to pet the dog, which I assumed was just to reassure himself or the dog during a thunderstorm.
Oh and one error message when I tried to have a group of sims travel. Odd, because the first travel action went fine. I don't know if the error came up because they were trying to travel to an empty restaurant or if the error caused the employees to disapepar from the restaurant, but either way, the sims did all shw up, still in their group.
