I came to realize I was lagging really bad earlier and when I went to dupe my items. It was lagging so bad that it was say <Connecting...> for a long time. I alt+f4'd as before it said connected and that's when it dupes. I did it 5 times in a row because of that lag. So if you are lagging that's a perfect time to do it when it is stuck on Connecting.
