Summary:

Aquifers are generated directly on the surface of the world (not cave entrances)!

This does not correspond to the Java version where no aquifers are generated on the surface of the world.

Steps to reproduce:

1. Create a world with Cave and Cliffs.
2. Explore the shores of water bodies.

Observed results:

Aquifers will be generated on the surface of the world.

Expected results:

No aquifers should be generated on the surface of the world (including aquifer fences; no aquifers should be generated at all).
