Re: [Fixed] - Siblings don’t recognize each other

I’m also having this problem. My married Sims couple have had 5 children now, I’ve made two of them playable, none of them recognise each other as siblings. In contacts they appear as friends or acquaintances. They have the option of flirty interactions. I can’t get the Sibling Rivalry story up as an option. 

in screenshot- Emily and Isabella are Evie’s sisters (lexi and Jarrett are their parents) but they do not appear or act as siblings.
