Yeah, that's the unfortunate thing with the map, there are like eight(?) different versions of it and it's a big download. So even if I fix the bug for the English-language map, I'm not sure I'm allowed to distribute it (certainly don't have enough webspace). I can't even tell people which locations to change in a hex editor because somebody with the Polish map is going to need different information than someone with the Spanish map.
Still, when I release my editor, you can all change it yourselves. I'll include a how-to in the faq. ("Choose File|Open, choose EU2 folder, go to View Connections, select Kexholm from left-hand list, select Karelia from second list, click Move up, choose File|Save"). I'll also try to address the Colorado River problem, but that one is quite a bit of work for the user and will be easy to get wrong.
