On the issue of sunken sims, twallan had said it is the clothes that they are wearing. I found this to be true, when one of my own sims came home from work and was sunken, I sent him to the dresser and had him change clothes, problem solved. Only thing is, when you see sims in town like that, you can't very well make them change clothes. From what I gather, it is something to do with the coding of certain clothes, not sure if it is only work related clothes, but it seemed to fix mine when he changed them. Maybe after Seasons, it will be resolved. This patch has so many different codes that is related to Seasons, so hopefully, some things will be fixed.
