Hey there, I know this REALLY looks like MC-179501 but the main difference is the version that happened and that it was in a "normal" village.

This world was, indeed, created back when 1.14 released and I used to play with a friend, but currently it's only a singleplayer server. I was just generating some chunks and I found a village that had the grass block layer almost entirely missing.

The world's seed is 4627038505985368139, location is shown on screenshots. If it's not reproduced and you want to take a look at the world just to make sure, I can upload it in another place.
