Big dirt walls in Large village house.

I spawned in using a seed of '404'. When I visited the village, there was a dirt wall in one of the houses. The house was stuck in a mountain. Coordinates are -245, 65, 216.

Found another one, in same village. Coordinates -238, 64, 233. Entrance was blocked off by a few layers of stone, and the wall contained stone and wasn't full.
