I was in my 1.14.1 world and I hadn’t loaded much land (because that was before 1.14 was out) so new villages would spawn. So I loaded it up into 1.14 and I found one really quickly, at first it seemed normal but when I got to the far side of it I was really broken. The pictures explain it best so take a a look. I hope you can fix this. 

Ps. As I write this I think it may do with loaded chunks and unloaded ones.
