New Incest Bug

After this latest patch (Feb 3, 2026, I believe) the new family tree system seems to have messed up some of the game's recognition of family members. I have a sim (Xochitl) who is friends with her mom's cousin's child, or in other words, her 2nd-cousin (Demi). My sim's mom's profile recognizes Xochitl as "Cousin's child", so the game knows she is related. However, Xochitl only recognizes Demi as a "distant relative" in the family tree, which is completely wrong. The family tree, according to Xochitl but not anyone else, has Demi's grandparents incorrect. Like, the game took 2 random sims very distantly related (and not by blood) and threw them together as mother and daughter. Now, the OG sim in this convo keeps autonomously flirting with the friend/2nd-cousin. I tested this without mods/cc installed too- still a problem.
