Game Crashes (without warning or error message)

I also have this, Game plays fine otherwise and finally allows me to use High shadows (I too get a long wait before the loading screen does anything initially), but at random times the game just instantly closes down... no error message or crash message - just back to desktop/EA App. I thought it may have been some CC/Mods but have tried with and without this and it seems I'm not the only one... Hope this can get fixed! :)

Having same exact issue ever since the latest update! I can sometimes get in and do a couple actions before it crashes but other times nothing - have tried to repair game in EA app to no avail :(

I had this happen to me once and it scared the living lights out of me. I will say I have not had it happen again. But I just make sure to periodically save my game just to make sure I don't lose a ton of progress. Esp now that my sims family has like 4 kids total.. Which has been a nightmare to manage. 

same problem the game loads fine then playing like an hour in or so the Game Crashes without warning and left with the EA App still loaded like nothing had happened it start happening after the update.

I have experienced that, but only when I haven't cleared the cache. In your Documents/EA Games/The Sims 2 Legacy folder you may see two files called "accessory.cache" and "groups.cache" You can delete those two files, the game will automatically regenerate them. I find clearing them out periodically has helped stave off crashes in my game.
