In a brand new mod-free save, Tai Lum and Mei Prescott do not have a father-daughter relationship if you look at their family tree.
If you look at the family tree of either of her daughters, Tai Lum is their grandfather through their mother, but when you switch to Mei, the family tree breaks.
I noticed this in my regular save when they got married. I checked all my mods and added one to prevent incest. Then in a test save with extremely limited mods, it happened again. So I made a brand new save that has never heard of the existence of mods, with a brand new sim, and switched to the Prescott household. It was not my mods. They just aren't related.
Please help. This is very much not a thing I want in my game.
