Key Items destroyed during HQ attack

[Saedriss]

I got the Red Dawn HQ mission and things got a bit out of hand and the key items (the Doom Red-Keycard looking thing, etc) were destroyed by explosions (they threw grenades on the bodies, trying to get my guys)

Will I have a new HQ attack mission in the future for the Red Dawn or is this a softlock ?

The mission will only stop appearing after you research the item itself so im 99% sure you'll get another one
