Necramech Immunity Duration

[IiMorioI]

• TYPE: In-game
• DESCRIPTION: When playing Banshee and using her sonar ability on the necramech to increase weak-spot damage the mech will (if it uses his immunity shield ability) stay immune until the duration of the buff from the player goes away. Unaware players may not figure out that they are the reason for this bug to happen and could lead to the mech being immune for over a minute or more.
• VISUAL: N/A
• REPRODUCTION: Simply debuff with sonar and wait until the mechs immunity shield is up and keep using sonar to see it wont ever go away untill your duration expires.
• EXPECTED RESULT: The shield should behave like normal regardless of any debuff on the mech and not last for the duration of your debuff.
• OBSERVED RESULT: The shield stayed on and the mech was immune until i let the ability drop off and have to re apply it.
• REPRODUCTION RATE: It happens all the time, iv'e rarely got the immunity shield with sonar active on the mech to continue his normal mechanics (no pun intended).

My Banshee is unmodded, so i can't test it, but are you sure you're pointing out the right issue?
Have you tried shooting it while your sonar is up?
I'm pretty sure that Necramech shields have infinite duration, and the only intended way to disable it is to shoot it (preferably in the back, so it won't reflect damage).
