Ropalolyst Health Keeps Resetting (Steel Path) and the specters don't shoot

[Portlalaland]

I'm not sure if it's by design or it's a bug. When I did the SP daily mission Ropalolyst, the health bar keeps resetting. I didn't manage to capture the reset. The video below was the workaround I found after 2-3 attempts to kill him with the canon when his health bar reached 0. I had to activate the canon as soon as the health bar gone. Notice that the bar went full again for a fraction of a second after the canon hit.

Another bug is that the specters like the crewmate just don't shoot (same video, but from beginning).

Please investigate.

Just encountered this bug too, the boss' health would just immediately fill up during the last phase when depleted. Steel path. Very very frustrating since it takes ages to chew through all that health.
