Here is my current version, please feel free to comment:
EDIT, new version: (Uranium is 1NW from Stockholm, but barely visible)
Changelog:
-Moved the Netherlands, German, Denmark and Baltic coast 1N
-Reshaped Northern coast of Scandinavia on some spots
-Moved St. Petersburg 1NE, added Neva river
-Moved the Gulf of Finland 1N and added 1 tile to the easternmost tip of it.
-Moved Ladoga and Onega lakes and adjusted the coast of the White Sea and the rivers nearby
-Moved Finland and Helsinki 1N, added Vantaa river
-Moved Sweden and Stockholm 1N, added river and hills
-Removed two westernmost tiles of Norway, compensated by changing mountains to hills
-Reshaped the ugly Gulf of Bothnia removed northern river from Sweden
-Reshaped Kemi River
-Changed the northernmost grasslands to tundra
-Moved the resources into more correct actual locations, added fur to Finland and Crab/fish & more oil to Norway (1 oil was too little)
There could be a river 1S of the Iron, but I didn't put it in yet, so that the spot doesn't become too tempting. Baltic and German resources can also use some adjusting.
I don't know what's up with the editor, but coast tiles and some other tiles (marsh mainly) are really distorted for some reason.
