Coordinates: -1260 / 80 / 1200
I found a snowy village that extends into a nearby mountains biome, and this particular mountain has several overhangs. However, the extreme terrain confuses the generation of the new village paths. Specifically, the paths generate both above and below the overhangs at the same X/Z coordinates, rather than only generating once.
