Villager Predestination helps to prevent exploitation of villagers for a more balanced minecraft experience.

Villagers, excluding nitwits, are assigned a profession upon spawning. Their profession cannot be set or changed by the player altering work stations.

Villager trades are locked in. Trades can no longer be cycled by destroying and replacing a villager's workstation.
