Profession Lock
This *server* mod prevents players from resetting villager professions and sales by breaking and placing their workstations repeatedly to get the best trades.
This breaks immersion and makes the game much, much easier.
With Profession Lock, the villagers profession is locked even if their workstation is broken.
Also fixes:
