Problems setting relationships in CAS

I'm having the relationship problem also. I had a baby child she aged up to a child then all of a sudden she's my sister, but the father is still her father.. I tried to use create a Sim to edit the relationship, but for some reason it will not let meme with mom and daughter, even if I do the cas cheat. But it will let me edit relationships within the father. Its really irritating.. I haven't played the Sims since the issue.

My problem seems to be that I have Don Lothario in a family with Dina and Nina Caliente, along with two children, one with Dina as a mother and the other with Nina as their mother. Both have Don as their father...or did when I created them in CAS. However when I move them into a house, the relationships get all messed up.

I've tried resetting the relationships in a few different ways, and it works up to a point. The problem is that the game won't let me have the children have different mothers while Don is father to them both, even though his relationship with the mothers s room mate and not spouse. Nothing I do seems to let the children have the same father and different mothers. I am not sure if this is an oversight or a bug, but it is very frustrating!

Ok so I've been playing since sept. Haven't had any issues with glitches that cheats won't fix. Until today... doing a legacy family (fist I've played through to gen two ha ha) but any was. My heir got herself a bf well he aged up so I put him in the fam and put him back to teen, got the bf/gf back on well today I get on after patching and it says they are just friends. Their pink bar is maxed out and so is the friend bar. But no I teraction to become bf gf again... and they are promised to eachother. So I go into cas to fix it and it says I can't change pre existing sims... any word on how to fix this?

Ok I think I have solved this problem @rkchick @‌mariesalias @albanie
This new patch has given me the right rsole today, from constantly crashing, to code being shown instead of text- to faceless invisible family members in peoples family tree that showed no identity (probably a result of all that culling of sims) to this family swap business.
- Anyway, this is the long winded way I finally got it to work. After much trial and error, the most successful way is to take the family you are having problems with and separate them into individuals- if you have a child, use the testingcheats - cas.fulleditmode cheats and age them up for the short term, so they can be split from the family. Now this is done- go back to manage these newly separate sims in cas- then save them out to your library. Do this with all the members in turn.
Once this is done, delete all but one of these sims from your game. Now just play the one remaining sim on their lot as normal- if you haven't already, put the testingcheats true - cas.fulleditmode back on. shift and click the remaining sim that you are playing with, and select edit in cas. Now from the create sim icon at the bottom, choose the import from library option, and bring each separated member back into the household- change the age back on any characters you have changed. Now starting with the mother/father you should be able to change their relationships to what they should be. Then save and play

Unfortunately you will have to reintroduce all these sims to each other again- but they do at least keep their traits. I just cheated the friendship/romances back to get them to how they were before- pain in the backside if they were very social before, but at least it worked. I have had to do this with 10 households now, and although time consuming, it has got rid of the invisible icons, and put things back to how they were.

Also found out why it was crashing so severely when I first started doing this- I was getting flooded by randomly generated townies again (I removed my mods because of the patch) so when I put that restrict townie mod, it suddenly stopped crashing which stopped much salty language I can tell you.

I shall try that right now. I was actually about to try the id thing to see if that worked or not. And it just makes me sad, I've had no issues yet besides this. And it just literally happened today. That's what I get for playing to elder which I've never reached because usually play on epic and get bored and play different familys ha ha. Thanks so much!

I tried the id thing and it was having none of it @rkchick It would let me set wife/husband but not any other relative setting

Gayy well I'm aging them up right meow so if I can't get the whole move em out to work I guess they don't really HAVE to be married. But it would be nice

Well randomly even tho they are not in a relationship at all it just let me propose so I guess that takes care of that. I appriciate your help!!

Hi I'm having this problem I think?? I didn't read all the way through so it may of been answered. So I'm doing a Greek Mythology legacy thing. I'm having Gaia (first generation) and Uranus (first generation) have Titan children which if you know involves eventual incest (certainly to get to the main third generation like Zeus). I don't have the incest mod so with the first two children (Tethys and Oceanus if you were wondering) I tried changing their relationship in cas from brother/sister to roommates but nothing happens?? I don't know if it's because they were born in world not made in cas or? If someone could help me solve this problem that be great. Also I used the cheat cas.fulledit mode so that's not the problem, and they were twins if that makes any difference.

You can't change siblings to roommates unless you delete their relationships with their parents.

Reviving this thread as I've just run into this issue as well -- have a gallery household (father + 3 daughters, and an unrelated father + son) originally with the correct relationships, and then suddenly two of the daughters broke off and became roommates to everyone else (while remaining sisters with each other).

Gave TwistedMexican's cheat a try and had absolutely no response from the game. In addition, when I try to edit the two sisters' relationship with each other, both "Sister" and "Roommate" appear as valid options in the dropdown but clicking "Roommate" does absolutely nothing. They stay sisters no matter what I do. The "relationship.destroy" cheat doesn't work on them either.
