How do I prevent my family tree from disappearing?

I've narrowed it down to the cat dying. After kitty passes away (RIP) the family tree deletes half of the children two generations ago and their descendants. I tried moving the cat out of the household to pass away in a different household, but the tree still disappeared. 

I have backed up the save so that hopefully this can be corrected. 

I have cleared my localthumbcatche and repaired the game it's still on going. No mods/CC are being used.

@Vivi_WillowTree I've had this problem recently as according to the family tree a sim doesn't have children yet he literally does -_- bugs are frustrating man.
