[ARCHIVED] Dead Sims being culled fro family tree although still ghosts

@crinrict@SimGuruNick I'm hoping that you're still looking for saves for this issue since I just spent a lot of time searching backups to find them for you.  Below is my description to go with the saves that you can find here: https://1drv.ms/f/s!ArPIGWJbTX1ve7TSR_XH-J-0K24

Tree Intact... In Newcrest top 'hood in the Taft household, Tristen Martinez as a teen has an intact tree with his parents, brother, and sister.  They were downloaded from the gallery so have no previous heritage.

Pre-Marriage Broken Tree... The same sim in the same household but now partway through his YA age stage, his parents are now gone.

Now... The top left household in Oasis Springs household Rover. After Tristen moved in and I saw his tree I knew it was broken because I was familiar with his older brother. I'd gone back into an old save and saved his parents into my library. I then added them in CAS, made them his parents again with cheats and killed them again with cheats to fix the tree. I also grabbed his brother and sister's graves for safekeeping. I noticed recently that the sister is no longer in the family tree. The odd thing is that her children still show in Tristen's relationship panel as a niece and nephew. You can find the parents, brother, and sister's graves in the Newcrest graveyard kinda stuck in a corner by the gate.

This bug is very upsetting to me considering, as you can see by the extensive Rover/Raines family tree, that I take heritage very seriously. I have other family households you can see since they are marked as played and my fear is that due to someone being culled from a tree, I will inadvertently marry a sim to a relative. I hope that these saves can help you.
