Turns out the RMGs are in the save folder. There were several broken provinces in this game, not just the one. The northern landmass, for instance, and some of the lower ones have some funny connections.
Can the random map generator be interfered with by other running processes? While the map was going up I was running uTorrent, resident protection AVG antivirus free edition, windowsblinds, watching an avi, browsing the internet and so forth. If that's the origin of the problem, it'll be easy enough to replicate and avoid. I hadn't noticed such random map problems when all I did was wait for randomization.
I'm uploading the savegame folder in the
7z archive format because its a free format with about 40% savings. I can up it as a zip file to, and probably will edit it in after uploading finishes.
The file can be found at rapidshare.
