Item Duplication Glitch
This is a bug that has been in the game for a while, that I thought would have been fixed by now. Basically if you set up a sticky piston like shown and put an item in the chest, it can be duplicated. How it works is
- Place item in chest
- Activate sticky piston
- While the chest is activated, pull out the item quickly and place it in your inventory (or use shift click) right before the chest is pulled back down
- The item you have pulled out will be in your inventory, while still being in the chest, effectively doubling or "duping" said item.
