When using the /place command to place villages, paths are replacing grass plants, causing them to be lumpy.

Steps to reproduce: 

1: find a flat area of land with grass plants on it. 

2: use the /place command to summon a village. 

3: notice that the paths are wildly uneven wherever there were grass plants.

Paths replace terrain blocks when they're generated, but they're also replacing grass plants. In places where the path intersects Tall Grass, the top block of the grass is replaced with a path block. These are not good paths. 

Edit: see second photo below. Paths can also generate replacing tree leaves. This is even sillier.
