Steps to Reproduce:

1. Create a new world with a set seed in creative
2. Go to the nether
3. Get 10 gold ingots and barter with 1 piglin. It is best to do this on the nether roof.
4. Observe the 10 transactions
5. Recreate that same world and do the previous steps again
   Observed Result:
   The trades are identical. This is due to a seed being set for the random loot the piglin barters
   Expected Result:
   The trades should be random every time.
   Note: This also applies with ore drops and mob loot
