Villager workstations resetting other villager trades

Destroying workstations of villagers who have not been traded with will change the trades of other villagers who have not been traded with.

 

Reproduction is not 100%. To test for yourself, put villagers in separate boxes with their workstations and destroy one of workstations. Keep track of the other villager trades. Occasionally the other villagers will have entirely different trades after destroying a workstation.
