Looks like I flooded Uletha, that's what the Coastline Maintenance says and that's what the map shows. I'm really sorry, it's just that I can't find the problem. It says that the coastline is intersecting itself somewhere on Geanina Beach, just that there is no coastline in this location... Please help... Or is there someone else who has flooded Uletha? Or does it take a little longer to render? Somehow the entire continent is flooded and it's probably my fault...
EDIT: Would you look at that... While I was writing, the problem seems to have solved itself. Now that's awkward.
