There are no water sources near the south ceiling of flooded caves and trenches

The bug

Water sources will fail to generate on the south side of flooded caves and ravines. This causes flowing water to generate in the places without water sources, and it can be annoying to swim around when the flowing water pushes on you when trying to explore the caves.
