I noticed a little thing to do with Naval AI.
I noticed that when I was trying to use chainshot to bring down the rigging on a ship, every time my ship went to fire, the enemy furled its sails and the shots went buy harmlessly, as soon as my ship had fired, the sails were un-furled and away the ship went Very very impressive that they could know exactly when my ship was to fire.. (they probably could see through all the huge holes they were putting in the side of my ship.)

I have only seen this so far with Pirates as I have not fought any of the other AI factions since the patch.

Very similar to the old problem with troops stopping just outside of canister shot range whenever you clicked from solid to canister.
