Two times in a row now, the game has hard crashed and booted me to the console menu when I push Raeniks into the "final stand" where the servitors start to die. I'm playing on an Xbox Series X, running solo. I was running solar warlock with Speaker's Sight, Song of Flame, embers of Singeing, Ashes, and Char, and using Dragon's Breath and Lost Signal for dps. I was able to remove a large chunk of the health bar in one go so I'm not sure if it's all the ignitions or just the damage. It's really discouraging for a solo experience to have this happen, though.
