Blacksmith houses in desert villages are partially made out of sandstone

The bug

Blacksmith houses in desert villages are partially made out of cobblestone and partially made out of sandstone. Them being made out of cobblestone is intentional (see MC-102606), but the sandstone mixed in with the cobblestone looks very weird and out of place.

How to reproduce

1. Create a new Buffet world and select Desert in the Biome selection menu
2. Search for a village that has a blacksmith house
   → The house is made out of both cobblestone and sandstone
