I have a trader hall in my world housing 40 villagers, divided into two separate houses with 20 villagers each. The problem arose when one of the villagers was turned into a zombie and subsequently cured. Since that villager was not restocking, I decided to remove his bed and station. Now that villager caused all of the other villagers unlink to their stations and beds. Despite efforts to reset the village by destroying all their workstations, beds, and bells, the issue persists. The villagers are able to sleep, but they are not properly assigned to their workstations. Notably, there are no green particles when destroying their workstations, and they aren't utilizing their stations even when in front of them. Does this mean they aren't part of a village? This issue seems isolated to this man-made village, as visiting other villages works fine. Cats spawn in the area, but iron golems do not. Additionally, there's a 38x38 area between the houses adorned with decorations. I wonder if this affects iron golem spawning. Interestingly, closing the game and reloading resolves the issue temporarily, but if one villager's workstation is destroyed, the entire village breaks, and no villagers can restock.

When it was working correctly, 4 iron golems spawned. 

Steps to Reproduce:

1. Construct a man-made village with multiple villagers.
2. Allow one villager to be turned into a zombie and cure it.
3. Attempt to reset the village by destroying all workstations, beds, and bells. then place the beds and workstations. 
4. Observe that villagers are not assigned to their workstations and do not restock trades.
5. Note the absence of green particles when destroying workstations.
6. Confirm that villagers do not use their workstations even when in front of them.
7. Notice the lack of iron golems spawning in the village despite meeting the requirements.
8. Close and reload the game to temporarily resolve the issue but observe the breaking of the entire village if one villager's workstation is destroyed.
