One of my YA's, Eric, just started his senior year in college.  When I checked his wants I was startled to see that he wants his older brother Evan to go to college.  The problem is, Evan is dead!  He died about 8 Sim days ago, killed by a cowplant while visiting another lot on the day before he would have aged to adult (i.e. he was still a teen at the time).  If Evan was still alive he'd be in his early 30's by now.  The game clearly knows Evan is dead; he's showing as grayed out in the family tree and does not appear in the family in SimPE.
I'm wondering if Eric rolled this want because he does not have a close relationship with any other teens in the hood?  Even so, you'd think it would filter out the dead ones  

Is there a hack to prevent wants for other Sims to go to college?  I seem to remember something about this but I didn't pay much attention at the time since I hadn't played Uni in a very long time.
