If I'm picturing the way it's coded properly, there's a certain script that checks to see if monsters *should* flee when they take so much damage, and it's set to disregard that if the enemy is mindless. However, a Turn Undead check should use a different script, which should force undead to flee, rather than ask the other script if they should. So, *IF* the game is coded the way I think it is, this update should not affect Turn Undead.
