What I expected to happen was...:
The water would turn the grass path into dirt or grass, or this would never have generated.

What actually happened was...:
Some of the paths were under water there was a small gap between the grass path and the water as the grass path has a smaller texture, there was air in some places where there should have been water and some problems with water generating in farms destroying crops.

Steps to Reproduce:
1. Make a new default world with cheats with the seed: 158499379088449
2. Teleport to -288 65 -800
3. Look around. I don't know how bug fixing or world generation really works but I think you should have the same problem as me.
