Mass Effect 3 Bug Banshee Invisible

I believe it happens when you knock it into it's passive mode (Walking, Warp throwing, projectile blocking state) whist it's teleporting around. I think it's similar to how the Fury or Slayer can become invisible if they die whilst teleport-dodging.

The Banshee's hitbox is still there and functional, you can see it sometimes if their aura is active. Just shoot them if you know they're there. Bug fixes itself when they start their active mode phase again (Teleporting around and can grab)
