There is supposed to be a grass field around the river, but for some reason it doesn't show up. I made it with JOSM and because a feature cannot have more than 2000 points, I decided to break it up into equal parts.

If you know how to fix it, please tell me, or please do it instead of me, if you know how, I probably mess up.

Thanks!
