A more detailed description, in case this helps. I set the length of the facial sliders to 4, and the only sliders on the first sim I created that were out of normal limits was that the eye scale slider was slightly higher than you can normaly make it and that the ear scale and height sliders were set to the new minimum. The following has been consistent across the three or four times I've tried this - on the second or third sim I make, the game freezes (usually when I'm on Create A Style). My mouse can move, but I can't click on anything or exit out of the game. I have to do a force shutdown on my computer, losing all my progress. Does anyone know why this is happening and what I can do to fix it?

I know one reason the game can freeze when in Create a Style is a bad pattern, but that would normally happen the first time opening it not after a few times. To save having to completely restart save each sim to the bin after you make them, I got myself into the habit of doing that because my game liked to crash at the most irritating times while creating sims or in build mode.
