I think I know the hairstyle you are talking about! Some of the clipping is really bad. Even worse once hats get added to the mix. The devs are pretty unhappy with it and trying to come up with a solution, but it might be one of those things that gets left behind because the cost of a solution is so much higher than the benefit gained.

Apparently they just got 6th place in the IndieDB Game of the Year awards, so thats pretty neat. I hope they win some real prizes once they are out of EA cos they've clearly worked really hard and done their best to make a game their players really love.
