After latest update to 1.20.80, the village center seems to change and no longer relates to a point of interest.

This is visible in golems and cats spawning outside expected points.

See attached picture where a village was built (in a realm) to occupy the square marked in violet.

Expected result: Iron golems and cats spawn within 8 block distance of the violet square (though due to farmland hoed around the village, spawns should be expected to occur only on the roof of the village).

Observed result: Golems and cats spawn in the square marked in orange (see gravel blocks I placed where golems were observed to spawn).

In addition, the spawn area keeps moving. After this image was captured, I ran the game for some time, once in a copy of the world, and once in the realm. In the copied world, the spawn area seemed to move slightly towards the village. In the realm, the spawn area seems to move slightly to the right in the picture. This movement happens slowly and incrementally.

Perhaps (but only speculation) the village center has become determined by an average of coordinates between beds. I had some beds about 100 blocks away and when I broke them, the spawn are seemed to move slightly again. But there may be no causation.
