[00676][T#177][Energy Core, Techhaven] Mobs not looking at you / no shoot animation

I tested this in the Energy Core 4 in Techhaven. When you shoot the little sentry turrets (the blue ones that are stationary) down to about 1/2 health, they turn around, looking in the opposite direction and stop moving. You still get dmg by them, but the shooting animation is only visible if you stand where they look. It is easily reproducable by just shooting them down to 1/2 health.
I can upload a fraps video if needed.
