Ah-ha I was looking for the 64-bit and couldn't find it thanks ill see if it works right now
I have a custom map in which I have a lot of custom trades that I set up by spawning them with command blocks.
I'm getting a very similar issue in which any item you get from the sell box instantly breaks (with tools) or just completely disappears when you right click with the item in your hand.
It's working thanks a lot
