For many runs this week, an Aeon Gauntlet'ed Hunter would go to finish a Champion, only to have the kill text not appear on screen, no points awarded, but the Champion would disappear for the Hunter and the other two fireteam members could still see them. This would leave the Champion not stunned anymore, and often cause the death of teammates from shield boops or overload retaliation spam. This happens to maybe ever 1/10 to 1/15 Champions, and I haven't been able to see if its happening to Champions in other activities or just this Nightfall, but it really stinks when it happens!
