I have tried archon boreal 3 times today . Each time he summons his ads (Aerolysts), The game completely crashes. Weapon is used changed between missions. glaxion, burston, Kuva hek. Only happens when i shot the ads or they were summoned.  Warframe - wukong EDIT: I did it.. I dont know the reason for the crashing. But i did it solo as a change. That worked for me.
