Step 1: Open your inventory.
Step 2: Click spawner and move it to your third inventory slot.
Step 3: Move the item(s) that you want to dupe to you first slot.
Step 4: Move the spawner from your third slot to your first slot, and the item(s) from your first to the third.
Step 5: Log out and then back in.
Your item(s) should now be duplicated. -
I found this around 2 weeks ago and I had a plugin dev send it in, but it still exists in 1.6.1
For video on how to do it here's a link, the link is unlisted and may only be viewed by people that click the link.

Serious dupe in creative? Where everything is infinite? Right...

You obviously don't understand the issue... _ I know you can spawn stuff in already, but the link you said it "Duplicates" has nothng to do with it. You can duplicate enchanted things as well using this method, where as I'm pretty sure you can't just spawn enchants when you're in creative. I know you get unlimited EXP but you can't just do something like /enchant <name>. That's why this is serious.

You have books and anvils and you can enchant every item with them, it's not a bug.

Also another "dupe" method: MC-138, also works as intended.

Okay whatever you say... Because apparently bugs aren't important.

Yes creative dupes are low priority, because in creative everything is unlimited.
Why did you make it public? This is a serious duplication glitch and more people don't need to know about it.
