The bug
Churches generate with cobblestone walls, but with sandstone stairs inside which looks highly unnatural (see screenshot). The blocks should be consistent.
This might be caused by the game attempting to replace every cobblestone stair in the village with a sandstone stair, including stairs inside the church.

I don't get why they don't just change the church back to sandstone.

Can we just update the villager generation process to use the structure file mechanic? Mansions, igloos, fossils and end cities already use the new mechanics.
Confirmed for 1.13.2-pre2.
Can confirm.
