May 12th: The family tree has not been corrected in this update.
A bug is occurring where the family tree is not displaying correctly.
This is likely due to the settings being based on EA's family tree configuration,
and the loading time is long due to the need for reconfiguration.
I am using a mod, MCCC, for relationship correction.
Phenomena:
1. In cases of polygamy, Sims with sibling relationships will show "Spouse: None." Consequently, single Sims will also show "Spouse: None."
2. In cases of forbidden or taboo relationships, they are replaced with "Stepson" or "Stepchild."
3. The family tree is not per household. Instead, there is no display method to indicate a starting point, such as "Spouse (Main)."
4. The game does not anticipate large families in long-term play.
Due to the reconfiguration based on EA's family tree configuration,
the family tree will not display correctly as you have played.
The save data has already been submitted in the "past," so please use that.
Oh my... it seems like your family tree is also so overstretched that it led to nowhere. Really wish the QAs and Devs will read all the comments under this thread before fixing the family tree issues
