Igoforunc09 and I tested his theory in the Event server and could not reproduce the spawn kills. When we went into the Dust server, I shot an RPG into the location he told me about and immediately, I got 4 kills with one rocket. Came back a couple seconds later and got 5 or 6 more kills with one rocket. Then I realized the game was locked in sudden death.
After changing the map out of sudden death, I could not reproduce those kills. This might be a glitch when in sudden death. Keep trying to reproduce this event while in normal game mode. If you are able to do so, then we will have to find some kind of solution.
Great job by all in finding this goof. Keep up the great work!
