The first many Super Shifts worked fine. But when doing SS on the 12 (around step 14, page 521 on) polys of the center oval piece the polys go shooting off into space. I have to do an Undo and try again but each time the same thing happens. I tried reloading the object but that didn't help. I also tried loading up the saved tutorial file from the DVD but the same thing happens. I played around with selection modes and the like but nothing seems to work.
Anyone come across this or know why it's doing this?
