Katherine. Can you give us a list of what's being fixed in SR4? For example, the multi channel magnet bug is a real annoyance. Here if you use a magnet on both a base figure and its clothes and save a pz3, when you reload the pz3, the magnet channels on the clothes get duplicated making the magnet effects duplicate. It happens on load, not on save or I'd write a small app to weed those out myself.
