sims two legacy bug

I loaded my game like normal when I noticed I had duplicates of each world without an icon they were and they also were the same save with my builds and families but when I loaded up my family it was an earlier save as my sim was pregnant I do not use any mods or cc. also I keep on getting object errors and when creating a new family I moved them into the home and during the loading screen I got and object error and when I loaded into the lot my cat was deleted from the game.
