OK, maybe I've been confused about the way kills are awarded, but I thought I was pretty sure that to tower and not give away a kill with an enemy GV or aircraft as close as 400 away, you had to be sitting on concrete.
3 times I had eggs in the air, bomb crater exactly where the enemy GV had been sitting while camping our spawn, and 3 times he towered after bombs were released, no kill.
bug or am I not correct about how that works?
