I was streaming Minecraft today, and when I tried to trade with the piglins, it wouldn't work. I threw Gold Ingots at the Piglins, and they were unresponsive. They wouldn't pick up the gold, run towards it, or anything like that. I tried using Gold Nuggets and Gold Blocks, but those didn't work as well. I even tried wearing all gold armor, but nothing happened. I had set the game so that Mob Griefing would be off, but that doesn't seem like it would be part of it since Piglin trading isn't really griefing (If this is the case, I'd like to suggest making a separate gamerule for toggling Piglin trading).
