This bug is being abused for String duping machine
Many people now rely on this to get unlimited string
In Minecraft 1.21, it is possible to take advantage of Crafter auto-compositing, allowing for unlimited Wool machines
Hopefully it will be fixed soon, and it has been delayed, which is not a good thing
Over time, this Bug will become a part of the gameplay and will evolve into something like 'Sand duping,TNT duping,Carpet duping,Rail duping'
The future will become irreparable
It's a bit embarrassing, when I was editing, the Edge browser helped me convert English into another language.
