Goth family

I remember people complaining so much about the premade families at the beginning when it came out, especially since people would say they don't resembled themselves from 'x' sims game.

Even if it took them forever, I rather do enjoy their new look opposed to before,  especially with how Cassandra takes on more of her mothers warm skin tone. Bella actually looks closer to her earlier counterparts in comparison to the other one (which you can find them on the gallery if you want them). Not sure if they'll remake any other families though other than the Goth's and the Caliente's (look far better than previously.)

The Goth and Caliente families were changed during an update to please some of the players. I disliked the changes they made too, so I put my own saved Goth family in the game instead. The old Goth family is on the gallery if you liked that look better.

What happened to Bella? Why did they remove her from the game? I loved her.

bev6usa, they haven't removed Bella. If you start a new game she is still in the save. The devs did change her look. If she is missing via the story progression, that is on by default that is an easy fix. 

 I saw her grave on the home lot on the sims 4

bev6usa​, they did add a graveyard to their lot when the house updates happened last year. Do you have story progression turned on for unplayed households? All are automatically turned on by defalt. There is a box that allows for unexpected deaths, just like there is a box that allows for adoption of sims, pets, and horses or allows for changes in friendships and romance. Start a new save and immediately go to manage worlds. Once there, go to manage households. In the unplayed household section the Goth family will appear with all 4 members. If you do not want random deaths to occur, that story progression box needs to be unticked.
