  • Reproduction Steps: We think it has to do with having more than 100ping in multiplayer and a chest (though we did it with a Stone Chest, we didn't check to see if it worked with other chests). Simply click on the item fast enough and it will duplicate the clicked item to the quantity of any previous item. We were able to dupe ores, bars, and gems (it copied the quantity of our stone). We were also able to sell the duped items for money.
  • Repro Rate: It works every time with any stone chest and any item.
  • Game Platform: Steam
  • Input Mode: Keyboard & Mouse

The save file and a video showing the dupe is currently attached to this post.

Hi @exotic igloo , thank you for reaching out to us! By "click on the item fast enough", did you mean taking it into your inventory then returning it back to the chest right away? Also, does it mean that the issue only worked if Ryan was the one to do it?

@edgy gulch Might be able to explain better!

Hi @sand shard, I'm Ryan in the video, this is a breakdown of what happened:

  • We accidentally discovered this while taking out some stone from this chest. We had a lot of stone (896 to be exact) and a few Silver Ore. I went to retrieve the stone but accidentally double-clicked, causing me to click the Silver Ore as well (since it appears after the Stone in the Chest inventory order). When the Silver Ore appeared in my backpack, it copied the Stone's quantity.
  • I'm not sure how this was coded, but tThere might not have been enough time for the quantity variable to have updated on the host-side in between my clicks due to the consistent 100+ ms ping delay.
  • I was putting the Dynamite and the Pink Diamond in and out of the Chest to duplicate the Pink Diamonds, since the order they're in the chest matters. In the video, I was putting from my backpack 20 dynamites back into the chest (left click) and one Pink Diamond (right click), then double-clicking the Dynamite slot in the chest. Each time I did this, 20 new Pink Diamonds would be added to the Backpack instead of 1.
  • I was able to do this consistently and across multiple Multiplayer sessions as my ping was always hovering between 120ms and 190ms to host (for reference, I am based in Luzon and the host is based in Java).

Hope this helps! We might be able to record a video from my perspective later if that helps.

Oh and we have not tested the reverse - I suspect that if you accidentally double click on an item whose quantity is 2 and the next item has quantity 100, 98 of the second item might disappear. We can also try this if needed

So, my guest and I finished the game, were messing around, and found the duplication glitch mentioned above we decided to test (for science 🤣). Using guest ping that is consistently above 80ms and two different item stacks in any autosorted chest (including auto sfh, shipping bin, and auto collectors that we know of), while spam-clicking the first spot, when the item stack get shifted over, the amount from the first stack gets pulled from the second stack regardless of quantity of the second stack. For example, if you have the first stack being 50 and the second being 20, if you spam-click the first spot, it will give 50 of the first and 50 of the second regardless of the second stack only having 20 items to begin with. The same thing also happens when the first stack is 20 and the second is 50. It will draw 20 from both stacks, but will give you the remaining 30 if you continue clicking. We are both on Windows Steam.
