Snow not appearing on active lot?

That fixed it! Thank you! 🙂 

@Jennym6  Do you have the same issue, snow not appearing on the active lot, as the original poster?  Does the game crash while loading only when Advanced Rendering is enabled?

Game keeps crashing only when trying to open it with advancer rendering. The world is covered in snow so are places around town but everything is just white, not snow? Only when I zoom in I can see that it is snow. But say if I go to a lot that is not a rabbit hole only placed tiles have “snow” but they also just appear white. Whereas on terrain it is just green grass. All the other seasons and weather conditions work fine. This is in sunset valley with no mods installed 🙂

This is a perfect example 

@Jennym6  I understand the issue, and it's an unfortunate result of the Advanced Rendering option being disabled.  When it's enabled, there's a separate issue, namely that whenever the snow depth is greater than zero, roads show through walls of any rendered building that isn't a rabbithole.  But that's beside the point.

When you enable Advanced Rendering, are you quitting to desktop after changing the setting and before trying to load a save?  Does it help if you delete options.ini, in Documents > Electronic Arts > The Sims 3, and try again?  If the game still crashes, please post the full specs of your computer: everything under About This Mac except for the serial number.
