The shot after getting the magic bullet was a headshot which also went through and killed another enemy, but not in the head - magic bullet was lost… IMO should have been upped to 2.
It’s because the shot when through the drone and hit the boomer in the chest. Kill feed has headshot then body shot. It’s prolly because you are using Embar which already collats without MB. If it were snipe or Markza I feel like it wouldn’t have reset.
Just to add, and you may already be aware of this but firing anything that does not result in a headshot kill resets Magic Bullet. This includes using a Repair Tool; and when planted grenades are triggered.
