Killing four Guardians in a single invasion or having a fireteam member do it is glitched! Did both several times and yt is stuck at 33%! Didn't even count for the triumph either! No matter how many times a fireteam member or I wipes the opposing team, (ALL FOUR) it want go past 33% or count toward Triumph! I've earned the gun & triumph many times over and D@mn it, I WANT BOTH!! Are you aware, BUNGIE of this issue and if so WHEN will it be FIXED!? I'm on PS4...
