Not only is the ejection still happening, there's an issue where the enemy NPCs disappear from various random members of the group, making it very difficult to do damage. I would love to finish this achievement, but its behavior is so random it's not worth getting in there and hoping that the stars align. If nothing else, a checkpoint that allows us to restart at the phase we last achieved would be a huge improvement that would make the other issue more palatable since you'll eventually RNG it and be successful. I'll pitch in on the pizza party to get this fixed! :)
