This is an extremely easy glitch to pull off in Terraria 1.4.0.4 for you to use since I have been told some of the dupe glitches in Terraria 1.4 have been fixed.
This glitch doesn't let you duplicate anything at all but for sure let's you duplicate some VERY useful items and resources. Hopefully this glitch can help fill your duplication needs in Terraria until another even better one is found for you all to use.
