The bug:
Piglins are unable to pick up any items thrown into a ground by a player (Not even gold items, which they're addicted to!!) Because of this, players would have to right click to barter with the piglins.
To reproduce:
Spawn a piglin
Throw an item a piglin would adore (golden armour, golden ore, or golden blocks etc.)
→ ❌ Piglins aren't able to pick up items
Is the
mobGriefing
gamerule set to false?
