[HUD disappearing in the Exploiter Orb fight [Fix Pending]]

Yeah, has been happening for at least 4 weeks now, and the latest patches have not fixed it.

When does it happen?
When Exploiter Orb climbs down into Deck-12 and starts her dialog, the HUD turns off. After the dialog I assume it's supposed to come back on.
But sometimes it simply stays off for the rest of the mission.
Happens irregularly, about 1/3rd of the time, in solo and multiplayer modes.

Player fixes?
I have not yet found  a way to fix it (death / operator mode etc).

What disappears?

• Ability bar
• Weapon Bar (ammo, magazine etc)
• Status Bar (Health, Power)
• Ability Status bar (effects, durations)
• Damage numbers
• HUD markers like waypoints, indicators for Coolan Cells, etc

What is still shown?

• pickup prompts (not residing in UI z-order level)

Problem carries over to other missions / environments: No.
Whenever I leave the mission, in the next mission the UI element are shown normally.
Playing and re-playing the Exploiter Orb mission will have not effect on the next Mission.
