Blurry mirror and crashing lots.

[MonSun]

This has happened before.
Issues:

the mirror in the CAS screen is blurry, when I try to create a sim my game crashes.
And when I try to enter a lot my game crashes.
help?

If you have hacks in your game, do you use Hack Conflict Detector regularly? It seems that a simple double instance of the same bhav can be critical.
If you have massive downloads of new meshes, consider that it can be a mesh overwriting another. Most commonly you get a nude body instead of a hair or clothing but it can be more serious. If the lots are also crashing, then it can be something that is being used by any sim inside this lot that became so corrupt that the game cannot handle it. It can be a hair, a piece of clothing or even a simple decorative object.
Strange that it is affecting exactly the CAS mirror. Mirrors have a special reflection that is separated in the gmdc. Check all the custom mirrors that you have downloaded or anything that use special reflection to start with.
Good luck!
