I am so sick of sieges. Nearly every single battle is fought in a siege in my games, the AI doesn't take a single step outside of their towns unless I spend several turns destroying every single town that they've got in the region.

What destroys them for me are the buildings on the map, the pathfinding is HORRIBLE, especially for cavalry and the AI. I just spent a 50 minute long siege against a thousand men, all I did was chasing them around the map as both my units and theirs got stuck around the buildings, forming lines scattered across the whole map.

In the demo, someone managed to remove the buildings in all of the preset battles. I'd like to do the same in the battles in the game, especially the sieges. I think what he did was removing or editing a file in the "battleterrain" folder, but I can't figure out what to do. I'd really appreciate a good answer, thanks.
