I've been having a problem ever since I installed the Sims2 Seasons.
I have University, Nightlife, Open For Buisness, Pets and Seasons installed.
I don't know if this should go into the Seasons problem section of this forum because I'm not %100 percent sure that it is the Seasons expansion pack causing this though it really does seem like it.
So I'm very sorry if I misplaced it.
I'm also sorry if a problem like this has been adressed in the stickies or
something and I didn't see it.
The problem is that when I create a sim and put the sim into a house their face gets distorted. It's mainly their mouths, but there's also some distortion
to their eyes and noses. Sims I created before and after installing Seasons
have this problem. Downloaded sims, however, don't have this problem.

You can see how they're suppose to look from their icons.
The girl with red streaked hair is a sim I created before I installed Seasons.
The girl with green hair is a sim I downloaded. You can't really see from her face/icon but there is no problem.
The guy is a sim I created after installing Seasons.
I've had this problem for a month or so and have been unable to find a situation like mine. I've seen one's simular, where the faces revert to a default face, and have tried the things suggested for them but with no results. I'm not very good at computers so I'm at a complete loss as to
what could cause this.
Any help would really, really be apprectiate xD
Thank you
