I had four different families saved that in my original play through with them they were siblings and I also saved their elder parents. I’ve placed them in a new world, gotten them all into the same household, and am using Cas.fulleditmode and can’t make them siblings again. I can only make the children siblings with the parents. Help!
I can add them to the gallery within the next day. In my original play through, I split the family into three households, and by the time I moved them to a new save the parents had died, so I created two new elders to be the parents of the adult sims. That's when CAS with full edit mode on only gave me the options of "Roommate" and "Sister/Brother" between the adults and the elders. And I couldn't make the adults siblings, except two which were in the same household and saved as sisters.
It will be in the gallery under my account: jessycaz. I don't have any other households uploaded, so the three will be the only ones. I could also put up the elders I made as their parents but those were just two new sims.
I'll put details about what their relationships should be in the gallery.
