Piglin trading
I'm not sure if this is in both games, but I know for sure it's in Bedrock. When throwing one piece of gold on the ground when multiple piglins are standing right next to it, those piglins will pick up the one piece on the ground, and each will give a item back, despite only having thrown 1 piece down. I'm assuming this is not attended, so I've decided to tell you this bug.
