Extensive Port Upgrades

[konny]

Didn't we change things around in the internal build by giving more trade bonuses after the third fleet is added? I think that was how we got around that limitation.

I am not sure if that limit really exists. Before changing the bonus of the extensive port, I always had hughe amount of extra trade income after building these, what shouldn't be possible when adding new trade fleets to the three existing. May be, only three fleets are displayed on the detailed screen but more can be used.

Nope. An easy way to see - look at a city which is nominally running four or six trade fleets (might have to be 1.0 or earlier, wasn't 1.1 supposed to fix this?). You'll see a nice chunk of new trade income projected for "next turn". Hit end turn, look at the city again, and you'll see that the current and projected future trade numbers are exactly the same as they were before. That fourth (or more) trade fleet is forever one turn away from actually trading...

As an alternate test, you could use the console to instantly complete a large port upgrade (nominally four fleets upgraded to six) and see if your trade income changes. I guarantee that it won't.
