Villagers are broken

Villagers no longer link to a work station.  I can destroy a work station and replace it and will not get the green linking particles.

 

A villager who has never had a job is now a cleric, even though i have no brewing stands in several hundred blocks in any direction.

 

 

Because the villagers are not actually linked to work stations i am not getting villager restocks.   Villagers also just wander around and won't move to a work station they are supposed to be linked to.
