Some questions.

Does the Sea Port building boost the production of cargo ships?

Does the marble wonder bonus apply to NW from ancient or classical age, that you are building in other ages?

And lastly is it just me or does the military advisor often not comment in the military power of you closest, and presumably strongest, neighbor. While still commenting on tiny Civ's on the other side of the planet?

1) I don't think so, but I'm not sure
2) I believe it depends on the wonder, and not on the age.
3) YES! This is so annoying! No idea what algorithm goes on in this guy's mind. "I have a status report on everyone except the guy who you've gone to war with 3 times in the past..."

Dear military advisor, I possess a force strong enough to wipe of the earth, I urge you to come up with some relevant information about my neighbors, they threaten our(and yours) very existence.

I sometime wish you court martial him for gross negligence and incompetence, and have him hanged.
