When using gold ingots to barter with a piglin, if you right-click more than once, the piglin will take the gold and give items equal to only one ingot. They can also attack after that with no reason (no minning gold, opening the triggering UIs, not wearing gold armor or attacking) I am not sure if they can take more gold than they should when picking it up, but im positive they could. Please fix that bug as you can waste gold if you are careless. You can reproduce it when on survival by: giving yourself 10 gold, find a piglin to barter with, start using the gold on it without stop right-clicking. You will see taht the 10 gold is gone and you ony take items from 1 barter. What should happen is that you shouldn't be able to use more than 1 gold per bartering.
