There’s a new problem with The Sims 4 Relationship Error Glitch when you’re using sims 4 cheats to fully edit sims in CAS where the relationship label between parents and children changed into siblings (sister / brother)
how to fix sims 4 relationship glitch ?
unfortunately we must wait the patch update in order to fix this bug
from the official said :
Graham Nardone @SimGuruGraham
“Hi, it’s something we’re actively working on. There’s nothing you can do about it currently.”
so avoid this glitch if you want to edit CAS, use the “testingcheats true” then “Shift + Click Sims + Edit in CAS” cheat to edit your Sims clothing and hairstyles. This cheat is the same as “using the dresser”.
or when you add a family to a house, dont use the cheat.. just ask others to move in from the menu. become friends then move in will be when you act friendly enough. then let them have kids normally.
a lot of players already complain about this relationship error on forum :
“yes its definitely a big or a glitch that hopefully will be fixed it definitely happens naturally and when using the cheats hopefully it will be easy to have the relationships easily chosen without restrictions in case situations like this happens because ITS RUINS GAMEPLAY WITH FAMILYS”
