Yeah.... Not so sure about it working just yet.

This also happens when a building spawns on the border of two or more biomes. Not sure why it happened here, as it is all in a desert.

Can you send me the world seed + coords?

I can't remember the coordinates, but Admist shows me (148, -4028). Any village may work, especially if it crosses biome boundaries.

You were at -737, -1451

Fixed in the latest commits (next release).
