Sims still dissapearing... again. The Sims 2 Legacy collection

Here is the problem : The **bleep** game still broken, right?. All the sims dissapeard everytime they visit a community lot. At least, that's what happened to me. 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.
