How to Do the Duplication Glitch in Cubic Odyssey

This duplication glitch in Cubic Odyssey requires two players and a chest. It lets you duplicate anything from regular ingots to upgraded extractors with attachments.
You won’t need mods, cheats, or complicated timing tricks… Just another person and a chest that’s probably about to become the most overused object in your base.
What You Need to Duplicate
Two players and a chest
To pull this off, you’ll need:
Another player (this will not work solo)
A storage chest or container
Any item you want to duplicate
That’s it. Doesn’t matter what the item is as far as we tested; blocks, gear, even tools with upgrades.
How the Glitch Works
Both players open the chest at the same time
Both players open the same chest at the same time.
Player 1 (you) takes the full item stack out of the chest.
Player 2 does the exact same thing at the same time.
Player 2 places the stack back into the chest.
Player 1 now closes the chest and can take the duplicated stack.
You’ll both now have a copy of the item. It’s not visual or temporary — both players actually keep the items.
How to Avoid Messing It Up
Make sure both players open the chest at the exact same time
Don’t delay the take-and-place steps
Only Player 2 places the item back into the chest
If you wait too long, the game might refresh inventory state and cancel the dupe.
Final Blurb
It’ll probably get patched soon, but for now, it’s a fast way to double your rare blocks, tools, or anything else shiny you’re hoarding (if you’re ok doing it, and at your own risk as always with glitches or bugs).
Just don’t accidentally dupe your storage mess too. One copy of that is more than enough.
FAQ
Q: Can this duplication glitch be done solo?
No, you need two players to open and interact with the chest at the same time.
Q: Does it work on upgraded tools or attachments?
Yes, it was tested with extractors that had mining upgrades and still duplicated perfectly.
Q: Will this get you banned?
There's been no word from the devs about bans, but like all glitches, use at your own risk if you're on a shared or official server.
Q: Can you do this with stackable and non-stackable items?
Yes, both work. The glitch duplicates the actual item instance, not just stack size.
