Adds massive cargo ships to the game, that function similarly to trains. Also adds deep sea oil, oil platforms, tanker ships, train bridges and other water based content.
On startup I get the error:
failed to load mods: error while running setup for entity prototype "or_radar" (radar): next_upgrade target (5d-radar-02) must have the same bounding box.
Sounds like 5D is trying to make every radar entity upgradeable, without checking whether it's actually placeable or a real radar. They need to blacklist or_radar on their side.
