I've been doing a lot of mapping around Narathiwat in Southern Thailand. I had the coastline running into the bay in the city and it seemed to make more sense to cut the sea off at the mouth of the river and convert everything from there backwards to be river (and with riverbanks instead of coastlines). However, since doing that, the islands in the rivers have now all become blue and are not appearing on the map.
I figured it was something to do with the direction of the ways, but I tried changing these to no effect.
Is there anyone more experienced in these things could have a quick look and maybe work out what I'm doing wrong
