Forum:Sims 4 family tree help

So, I created a Sims with a family, and I added the great-grandparents of Nia later on. (I created them in Create-A-Sim, then I used MC Command Center to add them to be the parents of Nia's grandparents, then used MC Command Center to kill most of them by Old Age.) But some weird things have happened to the family tree. Above Gerald, there is this unknown person with no picture in the parent slot for him. And when I click on Nia, it doesn't show her great-grandparents on her mom's side. Why is this? DarkSuicune2000 15:47, July 23, 2018 (UTC)

Okay this is getting ridiculous
Hello again okay so remember when I complained that half of the great-grandparents disappeared when I was clicked on Nia's genealogy? Well I returned from a trip and not playing Sims 4 for maybe a week or two. Now my family tree doesn't show the great-grandparent generation at all when I'm on Nia or her cousin who is in the same generation. (And when a click on a great grandparent, it still shows all 4 generations... It seems that it only shows 2 generations upwards now?)

Second, when I click on Victor and Carrie, it shows that Jeb (their son) and Astrid (Jeb's daughter) are not connected as father and daughter on the family tree and the unknown Sim is Astrid's father, but when I click on Astrid's or Jeb's genealogy it shows that they are related as father and daughter. I think this may have to do with the fact that I created the great-grandparents, Felicia, and Astrid in Create-A-Sim and connected them later on in the game.

Part 3
Okay so, after Patch 72, the problems from the second post are fixed. But Nia's great-grandparents on her mom's side still don't show up. DarkSuicune2000 16:52, August 22, 2018 (UTC)
