[FIXED] Children are their parents siblings

Update

I believe this bug was fixed but I’m not 100% sure

Problem

My Sims kids suddenly are not the parents children anymore but their siblings.

Cause

This bug is caused by the cheat cas.fulleditmode.

Solution

You can repair the relationships with a few cheats.

First you need the ID of both your Sims. Do the steps below for both Sims:

  1. Open the Cheat-Console mit ctl-shift-c
  2. Type testingcheats true
  3. Type sims.get_sim_id_by_name <Firstname> <Lastname>
  4. Write down the number you are given. It’s very long.

Then you can reset your Sims relationships

  • Type relationship.add_bit <ID Sim 1> <ID Sim2> <relationshipBit>

<relationshipBit> can have the following values.

romantic-Married
family_husband_wife
family_grandchild
family_son_daughter
family_brother_sister
family_grandparent
family_parent

Example

Susan has ID: 775464154248314888

John has ID: 775464154248314999

relationship.add_bit 775464154248314888 775464154248314999 family_parent would now make Susan John’s mother.

You can’t remove any values, only overwrite.

How to avoid

Don’t use the cheat on families
