After multiple testing, piglins who are equipped with crossbows are not willing to pick up dropped crossbows although the baby ones do, adults do not, and Piglins after hunting a hoglin do not perform the victory dance, Including the fact that it has only 10% chance to do so, after multiple testing, surpassing the 10% threshold they still don't 

How to duplicate: 

1. Summon or find a piglin with a crossbow
2. Drop a crossbow

Observation: piglin is not willing to pick up the cross bow 

Expectation: piglin should pick up the crossbow

How to duplicate (piglin victory dance)

1. Summon piglins and hoglins (piglins higher in population)
2. Piglins initiate hunt
3. Do this multiple times (more or equal to 10 times which should fulfill the 10% chance)

Observation: non of the piglins perform the dance 

Expectation: Piglins or piglin should perform the victory dance atleast once among the attempts
