A possible bug. I say possible because we are using mods to make the multiplayer have more people and stuff. So not sure if this works in the base game. But just in case...we found you can duplicate items by putting them on a table and picking the item up at the same time. Here's a fun clip of it. https://clips.twitch.tv/ThoughtfulSparklingChipmunkPraiseIt If it doesn't work in the base game without mods, then no issue I guess.
