I got two stories.
When I got the game...
I tried making a legacy everything was fine and I got to generation 3 with no issues. However my first generation sim was dead and buried in the backyard next to her late husband while her daughters still lived in the same house they started with. For a while my sims would get haunted by their mom , but suddenly after I updated the game I go back to my game and I noticed no ghosts were haunting me anymore and when I checked the family tree the mother and father were nowhere to be found.
That's the day family play died for me, can't say I didn't try family play without toddlers, but thanks to culling legacies have no purpose.
Second attempt with the sims 4
After I got back to my game after like 4 months I decide to go for rotational play, since family play died. I rebuilt a bunch of houses and added a bunch of households, couples, families, roommates and a few single sims. I have over 11 household made by me from scratch. I worked on this game all year long and it's my current game. When get together gets announced I think " perfect now all my sims can join clubs" . In my game the main goal is friendship so obviously all of them knew each other and I had a diversity of sims , therefor many clubs thought out. However I install the new patch go back to the game I've been working on all year long to create clubs and enjoy the new expansion pack, but no no no, my sims no longer have friends and have to meet everyone again.
I tried recovering my friendships to actually play get together and I made it after a few hours with some of my sims. The other half still don't know each other and I got bored and I haven't been able to play the game in days.
