Terrible pathfinding in towns

[Ignopotens]

Just something that always bugged me about RTW in general. What is the deal with the absurdly bad unit pathfinding inside towns? Why do the groups of buildings have invisible barriers extending outside their rings of walls? Why are my troops trying to march all the way around the block when there's a 100 yard gap between the lone hut, and the next group of buildings?

Especially annoying when fighting for town centers, the units don't fully engage, just sending 1 or 2 men to fight while the rest mill around, or even running out of the city center and then running back in when you order them to attack a different unit they're 10 feet from. This is most evident in towns where the center is bracketed on 2 sides by buildings.

Lastly, is there anything that can be done about this?

*edit: Also, I've never seen soldiers who were so good at running in only right angles around street corners, even if the street is just a dirt path and there aren't any buildings in the way.
