Does anybody know why the rendering with Osmarender is failing after updating a coastline in tiles where an island is?
I have got this mistake only with ways/lines from "source PGS".
The rendering of water is not respecting the coast way rule (land on the left side and water on the right side of the way). I tried to fix this error on Suances coast and finaly, I found out that the only way to get a correct rendering was to erase the islands in front of the coast and redraw them manualy. Hope this time it will work!
