Re: Roommate Public Affection Trait

@ammaaya, yes, I can see how that would be distressing! 😞  I don't think they intended for anyone to make their Sims' own family members NPC Roommates, so that is probably why this problem exists.  I did both a Search for this bug and check the lists of the known bugs and couldn't find anything on this yet.  It would probably be best if you were to make your own Bug Report here:  https://answers.ea.com/t5/Bug-Reports/bd-p/The-Sims-4-Bugs  

I couldn't find anything on the Step-parent issue in the Bug Report section either, but I've seen other people mention this as a problem.  However, if I remember correctly, this probably isn't considered a bug, but more of an oversight, since technically (genetically/biologically) step-parents/step-children and step-siblings aren't related.  However they are related socially! 🤨  Personally I think this should be changed in the game!
