there is clones popping up of some of my sims, they have the same name, traits, all that, but live in different places and have different jobs.
my sim just attended a party and a clone of her was dancing with another girls husband!
i also had one other issue, i adopted a stray dog and he got stuck under ground..
i do have custom content, but have never had this issue.
my town is a custom build one i downloaded also.
any ideas? i love this town, i love my sim & her house i dont want to start over!
Expansions installed: Ambitions, Seasons, Pets, World Adventures, Generations, Late Night

Do you have copies of those sims in your sim bin? (To be clear, that's the bin that is actually in game, rather than the library in CAS.)
And do you have an alternative to the EA story progression, like Awesome mod or Twallan's Story Progression?
And do you have any immigration going on to get your sim some neighbors?

IIRC, Awesome story driver does pull sims from the sim bin as candidates for immigration. (Probably on the theory that you have deleted ones you don't want to see, and prefer sims who look more like your own sims than the ones EA made.) This doesn't explain the buried dog, though.

http://www.modthesims.info/wiki.php..._3_Game_Problem should help with that. (Note that if you get to the point of testing with no CC, or with a vanilla game, this is NOT a requirement to delete everything. It's just temporary. And the first step is to check http://www.modthesims.info/wiki.php...em_Requirements to be sure your computer really can handle the game and the glitches are not a warning that something is weakening. If you aren't sure, http://www.modthesims.info/wiki.php...lp:System_Specs will give you a template to use to post here and ask. )

nope, no mods like that, only a mod to add any lot size
by the bin you mean the little bar of households when you're in edit town? there is! i didnt think they'd decide to come and invade my town though, I've never had that happen . ill try deleting them and see what happens
thank you very much for your reply, ill let you know how i go

okay i think you were right it's all okay now!
there is one that i cant find in the town so i can get rid of him but its okay
