I have no idea what has caused this.
Two of my elder sims in Strangetown now have SEVEN wants.
They're brothers, one of them graduated college Summa Cum Laude and the other one graduated but not with honors.
It's not from the extra want thing you can get after a good vacation, because this is the first time I've played this family since I've gotten Bon Voyage and I haven't sent anyone on a vacation yet.
Also, the memories are messed up. The memories say two of these sims have just graduated college Cum Laude, when infact they both graduated like 30 sim days ago and Summa Cum Laude. (One of them is the seven want one in the pic and one of them in the normal six want blonde woman, also they still both have their original graduated from college memories in the correct places)
