What happened was that while in creative mode, if I was to pick up ANY item with the mouse, whether it be a stack of diamonds, a tool, whatever, and I were to VERY quickly click in another spot in the inventory, and then click in another spot, it would glitch as if it were in both spots, and then it would duplicate. It's hard to explain, but hopefully this makes sense... Sometimes I find that it glitches out and the item just disappears. then if it were an enchanted item, you lose the item.
I discovered this glitch by accident, and I didn't expect this to happen. As an owner of a server I can switch between gamemodes, and this can be abused by admins if they find out about it.
Steps to Reproduce:
1. Grab the item you want to duplicate while in creative mode with the mouse.
2. Quickly click on a different spot in the inventory.
3. Then quickly click on a DIFFERENT spot on the inventory. It usually works best if those two spots are right next to each other. (If you would like me to, I can make a youtube video of it and post a link of it.)
Please let me know if this was helpful or if you would like me to make a youtube video of it if it was too confusing. If I indeed make a youtube video, I'm sure many people will come watch it and start duplicating things on creative/survival servers where they can switch game modes...

It sounds very similar to this issue, but it is not replacing other items when it duplicates the stack or other item. Also, I marked it as private as it says in the instructions of the best way to make the posts that you should make them private if it is an exploit, and I considered this as an exploit. I apologize if this was not an exploit in your mind.
Yes it's an exploit...in creative! Where everything is infinite!
