Sims 4 Not So Happy Play Thread & Neutral , No Bashing just your thought's

I like the game but I am a little disappointed that the family tree can't resemble what it does in the tree in the game. Like I think its really stupid that the 4th generation isn't even recognized or that like a step parent that has raised their spouse child from a baby lets say can flirt with them when they become a YA. Or that when sims marry into the family they aren't family.
