Columbia -- Colombia
Equador --> Ecuador
Portugese Guiana --> Portuguese Guiana
Rio de ***
--> Rio de Oro
Eire is missing (Pro-Allies)
Crete is missing (Pro-Allies)
Anglo-Egypt --> Egypt
Tanganeeka Territory --> Tanganyika Territory
Tsagaan Olom --> Tsagaan-Olom
Line Island --> Line Islands
And cosmetic changes that I would personally prefer:
( Pro-Allies), ( Pro-Axis) and ( Impassable) all have a space after the opening '(' but not one before the closing ')'. Either use space on both sides, or on neither side.
And maybe you could divert that seazone 5/6 line a little bit to coincide with the Amur-Korea border?
And if you really want to be perfect, a cosmetic change to make Quebec and New Brunswick border, to remove the ambiguity?
