Chests with the minecraft:chests/trial_chambers/reward loot table (which can be located in minecraft:trial_chambers/hallway/rubble) can contain unique item of vaults, such as the Bolt armor trim, the Precipice music disc and the Guster banner pattern.
Steps to reproduce:
Run
/give @s chest[container_loot={loot_table:"chests/trial_chambers/reward",seed:11}] /give @s chest[container_loot={loot_table:"chests/trial_chambers/reward",seed:15}]Place down and open the chests
Observed result:
There is loot that is supposed to be exclusive to vaults in the chests.
Expected result:
There is no loot that is supposed to be exclusive to vaults in the chests.
24w36a also has this problem. Found Trident, Mending, and other vault-specific loot.
