I found something incongruous in the Diplomacy options, you can trade "World Map", that's wrong. You NEVER are able to see the Europe map for example. It should be something like "Colonial Map", "New World Map", etc.

Considering the rest of whats wrong, its really the least of our worries i think... even though u are absolutely right.

Yes, but this one is easy to fix in some patch/mod :)
