Professions Lock Mod (1.21.7, 1.20.1) – Minecraft Villager Trade Fix & Balance

Professions Lock Mod (1.21.7, 1.20.1) is a lightweight yet powerful server-side mod that fixes one of the most commonly exploited mechanics in Minecraft: constantly changing a villager’s profession by breaking and placing workstations. With this mod, once a villager chooses a profession, it becomes permanent even if their workstation is destroyed. This change prevents trade farming and promotes a more immersive, balanced gameplay experience for players and server admins alike.

In vanilla Minecraft, players can repeatedly place and break workstations to reset trades and get the most favorable deals. While useful, this undermines the game’s design and breaks immersion. Professions Lock Mod restores integrity to the trading system by making villager professions persistent.

Features:

Locks Professions: Once assigned, a villager’s profession cannot be changed even if their workstation is removed.
Prevents Trade Abuse: Stops the exploit of cycling workstations for perfect trades.
Immersion-Friendly: Creates more realistic and balanced gameplay by making villagers consistent.
Bug Fixes Included:
- Fixes issue where cured villagers would work at incorrect stations (vanilla bug: MC-177505).
- Stops nitwit villagers from gaining a profession (vanilla bug: MC-146891).
Server-Side Only: Does not require installation on the client side, making it ideal for multiplayer servers.
