Summary: I was testing some custom POIs (not in a western town) and decided to go look at the western town. I found a town that was flooded, plus a road that went under a massive lake.

Wow, look at all the water. I must have left the faucet on. Seriously. There's a giant lake, which is pretty cool, but it seems to have flooded a western town. (See screenshots) Also, there's a road under the lake (but no tunnel).
Detailed steps to reproduce the bug:
1) RWG, Seed "ZZ2", Max Cities/Towns, Max Wilderness POIs, rest default. Custom POIs in the Prefabs folder.
2) Generate World
3) Load World, etc.
Actual result: (description of what is occurring)
See above. Also, relevant files (screenshots, logs, copy of world, etc.) found here...
Expected result: (what you expect to occur)
Big lake seems fine. Flooded town unexpected. Road under lake seems undesirable.
