Please use this thread going forward: Can't set two mothers/fathers as parents in CAS | EA Forums - 11952388
So I decided to do some tests on this (since I had mods turned off anyway testing a different problem I had) and I can only recreate this when an unmarried Sim adopts, regardless of gender. Steps I took to test:
1. Create household with two male Sims, set them as married, give them children in the following ways:
a. Create another random Sim in the household, make them a child, assign their relationship to both adults in the household as father.
*Success, both are now father.
b. Play with genetics, using both adult male Sims
*Success, by default both are father.
c. Place in household, have one go to computer and adopt.
*Success, by default both are father.
2. Create household with two female Sims, leave them unmarried to see if it makes a difference, give them children in the following ways:
a. Create another random Sim in the household, make them a child, assign their relationship to both adults in the household as mother.
*Success, both are now mother.
b. Play with genetics, using both adult female Sims
*Success, by default both are mother.
c. Place in household, have one go to computer and adopt.
*Failure: Child belongs only to Sim who adopted
3. Create household with two adult Sims, one male and one female, give them children in the following ways:
a. Create another random Sim in the household, make them a child, assign their relationship to both adults in the household as mother/father.
*Success, both are now parents.
b. Play with genetics, using both adult Sims
*Success, by default both are parents.
c. Place in household, have one go to computer and adopt.
*Failure: Child belongs only to Sim who adopted
In all of those cases did you check if they were listed as parents in:
1. Family tree
2. Relationship Panel
3. Profile Panel
4. CAS
The most likely place to show is the family tree, but the relationship hovers and the profiles are often mismatched and CAS has also been a problem.
