I have a large legacy family I remade for The Sims 4. The family consists of three YA siblings, their spouses and one sibling's teen son.In the CAS demo, I made all the YA and set their relationships fine with no problems but when I added the teenager to the household in CAS when I got the full game, I had issues setting his relationship with his father (his father's wife is not his biological mother). The father's relationship list on the side showed his son as being his son, but the son's showed his father as being a roommate and it would not change when I tried to set it to father.Eventually I gave up and moved the household into Oasis Springs. I looked at the relationship panel for the father and somehow, his son was showing up as his brother. I evicted the family, pulled my saved copy of them back out in CAS and tried to redo the relationships. This time, I couldn't set the father's relationship with his sisters. Same issue as before where I would click on Sister but it would stay as Roommate.I'm really frustrated because there's no way I can play a legacy challenge with relationship issues like this. Any help or suggestions would be most welcome. This is the first serious problem I've run into with the game. I've been playing almost 24/7 since September 2nd and it runs beautifully with no serious bugs but this one is serious and I just ran into the problem today.

I made a post about this yesterday but got no answer. It's been happening to me as well and I'd really like a fix for it because as you said, it's really frustrating.

Same issue for me. I noticed it when I moved out a few Sims from their parents house (all YA siblings as well) into different houses and those Sims then went to have children and the children did not show up as the grandchildren of the parents of the YA siblings. Then later one of the YA siblings had their mother listed as their sister. I really wish this would get fixed as its stopping one of the parents of the YA siblings to achieve his aspiration (one of the family ones requires four grandchildren). But I have a hunch it has something to do with moving families around. Hope this gets more vision will watch this thread! Edit: In the meantime I've found a fix (hopefully) haven't tested it yet but if you use Shift+CTR+C to get the cheat bar up and type testingcheats true and then press enter and then type cas.fulleditmode and then enter again and shift click on a Sim you can edit them in CAS with full functionality and edit the relationships. I will test when I get the time and post back on the results. Good luck!

I've had issues with this as well. You can create a child from two male sims, and set them both to the father, but when you get in game it sets one of them to either a brother or roommate. Also thanks 3mmagreen for the cas.fulleditmode. I didn't know that one existed.

No problem, but I've tested it and it doesn't solve the problem for me sadly. The option is still grayed out or doesn't select properly and wont change their relationships. It says can't change Sims that have already been created (or along of the lines of that). Tell me if it works for you though. Will keep looking for a fix in the meantime.

This is going to be really problematic for legacy players yikes. Bumping this again because this NEEDS more attention so we can find a fix.

I have this as well. For some reason my sims son is now her brother. I even moved them out of the house and remade the whole family in CAS and it still won't let me make the kid her son....

I am having the same problem accept that my family's daughter was born in game. I didn't even create her in CAS. She was born in game, and suddenly, as she grew older, and into an adult, that romance options were coming up with the parents. I sent them all back to CAS and realized she was not the daughter of either parent but was listed as a roommate. and same thing... I could not change it even using the cas.fulleditmode cheat, it just said: "Cannot edit pre-existing sims." Is there a fix yet EA?

I'm having this issue as well. It's really frustrating. I'm a legacy player, like, that's the reason why I play this game. Ugh. I give up on this game entirely until they fix it. I'm so frustrated. What a waste of $$

This is so coplicated! Why is everything so difficult on TS4?

In this case, because they didn't include tools for fixing bugs they hadn't found yet.

If not for the relationship-breaking bug, there'd be no need for the complicated console commands. It's unfortunate the bug appeared, but it's hard to fault EA for not making it easy to fix the side effects of an unknown bug.

This works. It takes a little typing and writing down, but it works well. I used it to make ties between the Landgraabs and Johnny Zest. I got it backwards first, so if you get it backwards, just do it the other way. Note that you have to do it for both Sims you are making the relationship between.

Edit: Doh. I should have read the whole thread. But anyway, it DOES work. You just have to be very precise. The Sim ID numbers are LONG.
