Sims 2 Sim Deletion Bug

I've had the same issue. I spent 6 hours playing and had a kid before saving, exiting, and turning off the computer to go to bed. Came back today to load in and the kid is just completely gone. It's still there when I click on the house in the neighborhood, still in the relationship panel, still in the parent's memories, but the kid is just gone. Not even in the side bar to the left. I've added the game to the exclusions for the above so hopefully that helps it not happen again, but is EA working on a fix for this bug?

The problem still existing... here is what happened to me:  All the sims dissapeard everytime they visit a community lot. The loading screen hangs for several minutes... even hours, and if you restart the game, everything will be gone. No matter if you save the game. EA needs to fix that bug ASAP, otherwise the game will be unplayable. Does anyone else have experienced such a thing? :((

In details: I created my own household. I spent several hours creating the perfect house. I saved the game, and I decided to sent one of my sims to Downtown... such a fatal mistake I guess. When my sim tried to return to her home, the loading screen hanged for a ridiculous amount of time... So I decided to restart the game. (I had saved the game, so in my mind, I thought that everything would be ok) Guess what? The entire progress went directly to the bin.

Edit: I found a solution indeed... Fortunately, Steam refunded my money. That's all... This game is broken as hell.

I got the new Sims 2 legacy collection and my saved games just keep getting lost everytime i restart the game. Its like i am starting a new game from the begining, with all the tutorials and messages appearing. Also the premade Neighborhood townies are not visible in the list where you can create a new family or place a pre existing. I have tried deleting the whole folder from the my documents in order for a new one to recreate as i have seen that this works for some people, i have uninstalled one drive and nothing has worked. I dont know what else to do at this point.😪

This just happened to me, too. I played for hours and carefully plotted my neighborhood, only for this to happen. I want to hope this can be restored, but I don't know, and I feel like I wasted all that time. I've attached my entire Log folder here, hoping that something can be done about it. The character was a toddler named Catherine Goth mate54 (I hope I can tag you; I want to make sure you can see this, and I'm feeling desperate)

Also has happened to me this week, was hoping with the recent update that this would have gone away... 

This has happened to me several times at this point, including this week, with no OneDrive use or mods.  I can't play this game if my sims keep randomly disappearing.  I'm really hoping this gets fixed because what is the point of re-releasing the game if we can't actually play it.

Have you tried adding the sims 2 to the exclusions list in your antivirus software? That's what fixed the issue for me. Hopefully it helps you too.
