Empire: Total War devotees will be more than aware that, even after the game's been patched, there are still some glaring issues with the game's AI. Guess it's time for another patch, then!
There's a wide variety of minor fixes being made to the game in late September, most of them to do with improving the enemy AI. Two in particular stand out as being key, namely one fixing your troop's use of cannons while defending a fort, and the other improving AI when moving inside a fort and using ropes.
They're the two main things that made viable siege warfare nearly unplayable in the original release of the game, so hopefully in a few weeks time we won't ever have to complain about them again.
