I'd take a closer look at Modding the CPS social workers out of the game as those NPC ones removed children from a few of my oldest Modless games and those saves ended up getting corrupted.I lost two when errors occured while saving and the other one when It had a UI failure and refused to open so I deleted it.I always use save as except on a brand new game the fist time I save it and I rename each time I save.I am also playing my game very heavily Modded to remove the issues and fix glitches like the broken automated school assignments or the broken "story progression" commonly known as the EA bugfest.
