Why does the AI break it's formations constantly?

[AlphaDelta]

Does anyone know what specifically needs to be edited in the AI files to prevent the AI from breaking it's formation and crashing units through one another. All I want to do is make the AI stay in formation, advance in formation until they get to within x meters of the enemy, and after a certain number of shots, engage in melee. Is the AI so entirely broken that this is impossible for it to line up an army and march them forward in a straight line until they are parallel with the player?

Afterall, what's the point of having a formation if the AI goes from 100% formatted to 100% mess in less than 3 seconds?

The data/battle_config.xml file affects how units skirmish and charge (along with siege equipment movement and how long you need to hold the town center for). Changing 'wall reform' and 'unformed-charge' parts may fix your problem.

Also the data/config_ai_battle.xml file affects how the AI attacks.
