Village houses can replace half of tall ferns

the seed of the village?

As stated above already, please provide the seed + coordinates of where you experienced this issue.

Okay now I'm very confused
I logged into a copy of that world with the same seed, so I could try find it faster in creative, and found the place again, but the fern wasn't there.

I can see how this could seem like I used /setblock, but the above genuinely happened in my world.

Seed is 493833753420856

Co-ords are 3300 63 680

Not sure what other steps are necessary to recreate it, as it seems that simply going to that location in that seed doesn't recreate the issue for me

I'm unable to reproduce this issue using the provided seed and coordinates.

Could you please check if this is still an issue in the latest version?
