Neutral Units: "Fleeing" battle

[Shamanruler]

Is there a way to make it so neutral units don't flee once there health becomes low? I've checked gameplay constants and edited the Stats - Can Flee option in Object Editor, but with no luck. Any ideas?

Neutral units ignore non-tower buildings, and will flee from towers if their health is low. This was made by blizzard to prevent neutral units killing your base in the melee game. The only known way to get around this is to make all your buildings mechanical units.
