Sortie Defense - Operative Shield Bug?

[(PSN)crashteddy03]

I noticed the other day while doing a Sortie Defense mission that the Operative the team was defending was taking damage to health even though they still had over half their shield remaining. At first I assumed that the mission was under an Enemy Elemental Enhancement and that they were being dealt toxin damage. But when I rechecked the mission afterwards that modifier wasn't applying. I think the enemy faction was Grineer and there were no Nox in sight.

I saw the same thing again the following day with Corrupted enemies and again no Elemental Enhancement.

Is this a bug or does the Operative's shield work differently to every other shield in the game?

Bumping this thread because I noticed this again in the rescue mission of today's Sortie. The hostage was taking damage to their health while they still had 80%+ shield remaining. Rescue mission, Eximus Stronghold, no Nox or other toxin damage enemies (that I could see) nearby.

Am I the only one who has noticed this?

Slash procs are possible.  The operative doesn't have much more HP than most frames, so despite the damage enemies deal not being enormous, an occasional status effect would be noticable.

Hmm I hadn't considered Slash procs, I suspect that you may be right. It's a shame we can't see what procs (if any) are affecting the operative.
