Desert Spring boss gauntlet not progressing

I am trying to clear the boss gauntlet from the Desert Spring boss but it does not seem to progress.
It is stuck on a position and it is not moving.
Leaving the instance wont help. Leaving the area where the boss is in and return does not help.

I got the same issue … it stuck during travel alley to the final shot down… helpppp

Ok. I overcome this bug by going back to the beginning of the alley until you can’t go back. Stay there for a tick, the go back … ensure the scorpion tail moved away from where it got stuck … that seems to unclog the bug
