This is an excellent mod, thank you for your hard work! I have one issue I've encountered though. When I set a tile to be a navigable river, it does not show up or act as a navigable river in game. Weirdly, the tile tooltip says it is indeed a navigable river. I've tried with multiple different maps, both creating my own and modifying YNAMP's Greatest Earth Map, and I have the same result. I also tried just making the tiles I want to be navigable rivers into flat navigable river floodplain tiles, and that did not work either. Is this an issue on my end, or is that still a work in progress? Either way, the rest of the mod works wonderfully, so thank you very much!
