A shortish problem and question.

Problem:  Sometime prior to the AM update on the 13th one of my sims became victim of the "parent of some random vacation locals" bug.  I didn't notice this till yesterday when I finally got about to having him knock up someone (invited to move in foreigner) and took a look at the family tree for the first time (Unmarried, I never twigged to the fact that 'ask to go steady' had stopped showing up).  I was reading another thread about this problem and its been indicated that babies from this situation tend to be a lead up to a BFBVFS.

Question:  While the bug is squashed in AM now, and my AM is at the latest version, will this legacy fuckery of my family tree/relationships still eventually cause a BFBVFS even if I fix the tree/relationships?  The oldest save I have of this neighbourhood has the randomly added vacation locals in the tree, but before the affected sim started making babies.
