I have run exploiter orb 5 times in a row and each time I destroy all 4 vents in phase one. After this, however, instead of moving outside to wait for me the boss gets stuck in the mountain next to the exit door and the second phase never starts. I go outside and I can see her wiggling in the mountain. The frustration of not being able to do the fight is further compounded by the fact that exploiter orb is part of nightwave this week. If anyone has a fix for me I am all ears, I have restarted the game twice and no dice.
