This isn't really something that will keep you from dying or pile up glitch but I was playing a game of zombies and noticed we had all three parts for both shield and Ragnarok. So we decided to build. getting to the point here I guess we built the Ragnarok at the same time we had 2 locations of them and tested it with the shield and had 2 of those. just thought I would share this with who ever thought this would be helpful.
