Town Still Keeps Trying to Populate with Emigration/Immigration OFF.

I've had far worse issues than that once when my Modless game filled Sunset Valley up with over 1000 resident sims not including the over 300 students unable to enter the school to attend classes which resulted in one child being taken by the social worker and caused corruption in that save.I've had the EA bugfest overload my towns badly in other saves or just plain ruin the games and glitch other saves out with deciding that teens could become pregnant without aging up first which resulted in my deleting the saves.
