The bug

Directly giving a piglin a single gold ingot in survival does not grant the "Oh Shiny" advancement as the player is no longer holding any gold ingot.

To reproduce

1. Have a single gold ingot
2. Spawn a piglin and go to survival
3. Directly give the piglin gold
   → The piglin is distracted but the advancement is not made while you are holding nothing
4. Have two gold ingots
5. Spawn another piglin and go to survival again
6. Directly give the piglin gold
   → The piglin is distracted and the advancement is made while you still have a gold ingot left
