There is a dirt block at the bottom of the hay in the village.

(i)It is more convenient to find bug by using flat preset of non-dirt materials.

This is not a bug, i think its "Works As Intented"

@Andreaslag Why not?

Someone here?:flag_on:

It doesn't really matter whether that dirt block is there or not anyway, it's part of plains villages (plains has grass/dirt (when a block is on top of it) as a surface material).
