Can't drain armor from new gunners crew

[Redwyrm]

Not sure if that's a bug or intended. I hope it's a bug, because it's quite annoying.

And i am talking about new gunners on board of grineer crewships.

I'v tried it in particular with Hildryn's #2. Anyone but a gunners get their armor drained to zero. Which can be seen but their health turned from yellow to red. But gunners seems like just immune to that effect. Not only her health bar remains yellow, and she didn't seems to get any extra damage. But Hildryn also seems not getting here shield buffed, as if no armor was drained at all.
