On the home page and avatar design screen larger (taller) hairstyles get cut off. Just aesthetic, but it would definitely look better if the hair wasn't cut off. It's happening for me in Firefox and Chrome and I haven't tried in Safari.
We're redoing the avatar system right now (as opposed to gardens which we *plan* to redo soon) and this will be addressed when that's done. We'll revisit after it's done to see if there are any other display anomalies like that. Sorry and thanks, Badger!
