Villagers reset their workstations when a player sleeps in one of the village beds.

I discovered this bug in my "emerald farm", each villager is imprisoned in a "cell", with their associated workstation right in front of them (see picture).

When I created the farm, I made sure that the villagers were indeed associated with the workstation in front of them, the particles appeared well for the villager and for the workstation I had associated with them. Moreover, they were updating their trades after a certain period of time.

But at times all the villagers would lose their workstation and get another one.

After a lot of time and testing, I discovered that it was every time I slept in the bed associated with the village (there was only one for the village). When I sleep in the village bed, all the villagers reset their workstations, when I sleep in a bed that is not associated with the village (much further away), the villagers keep their workstations (as expected).
