Otherwise if you dragged an App off of the Launcher to the Home Screen it stayed on the Launcher and "doubled" the icon on a home screen. The update essentially put it back to the way Android works so it isn't a bug.
My Stock Messaging App loses my Contacts' pictures every time a new text comes in. The pictures are all coming over from Facebook but changing them to Google does noty fix the behavior. Eventually they all return but sometimes I have to force it by opening the contact, clicking on edit, then clicking on the person's photo and re-selecting the source that I am pulling the picture from. Very annoying.
