if you drop exactly two gold ingots in front of piglins they will pick up an ingot and trade but the gold still appears on the ground as if there are two ingots still left when they have only picked up one. if you go to pick up the gold you get the correct amount of one gold ingot. this means the problem is only visual making no difference to actual gameplay and no overpowered glitches. i just thought it would be best to let someone know to make for a less confusing interaction with piglin bartering
