Villagers think their bed is a random spot

While flying around i found a village, and as I normally do, tried to get the villagers safely inside so they dont get killed. These two villagers insist on standing in the same spot and even when scared away by a zombie, will immediately return to stand there again when I killed it.

Edit: theres multiple other ones doing it too, such as the two in the background to the left

Edit 2: So I died to an iron golem and when I came back they were back to normal? Perhaps it had something to do with their night pathfinding? Or perhaps the chunks being unloaded and reloaded (read previous report)

Edit 3: so yea, I hung around until the next night and their doing the same thing again. Edited title.

Edit 4: It seems like the chunks reset randomly for no reason so the village is new but the entities are not?
