I haven't been making changes to the version I linked earlier, this is the most current version:
https://www.warlight.net/SinglePlayer?PreviewMap=38859There was a problem with Mersin(Turkey) connecting with Linassol(Cyprus), and Istanbul not connecting with the Aegean Sea, but those have been fixed. I haven't found any other errors in the sea connections.
If there are any I'm unaware of, I'd appreciate specifics. For example, I still don't see the issue with Socotra.
