In a multiplayer game if you have one player placing an item on a table another play can take the item off at the same time the other person picks it back up which dupes the item. My friend and I found this while playing today and were easily able to dupe a large amount of items in a very short period of time. I have a video but I don't know how to upload it because it's an mkv file, if anyone knows how to upload an mkv file let me know and I'll upload it here. This currently works in 1.5.1
