Grustrag Three not sending any message after 5 invasions

[Draegan]

Hello Tennos !

I'm worried about our friends Grustrag, it has been month since I did not see them during grineer missions while I'm tagged.

Plus, is it normal if I do not receive any message from them anymore once I do 5 invasion for the corpus ? Like the Stalker do ? (Your actions have consequences...). I even tried 12 consecutive invasions mission, no messages. 

I know it's a spawn chance in the first 5 minutes but still, their silence in my inbox suggest me there might be a bug somewhere maybe. Do the grineer stopped the mass production of them ?

 

(I really need that Brakk receiver btw, gotta rely on those beacons I guess)
