Archon bugged against Master Mira

While playing against the Master Mira AI, I summoned an Archon, upon directing it to the enemy core, it proceeded to ignore the enemies attacking it and try and continually move through the enemy core, resulting in it's death.  After restarting and summoning another Archon, it would strafe around enemies and very rarely shoot, and while retreating it would occasionally stop and do nothing, then proceed to keep moving, resulting in it's death again.  Using the Archon against the other Master AI's works perfectly fine.
