Heroic firefight on temple

This is the second time I’ve gotten temple on firefight, in the last 24 hours where on round 1 where you get “kill 100 grunts”. Both times we have had around 2 or so more minutes to spare and there is still 8 grunts to be killed, but there is none to be found AT ALL. I play firefight way to much and this is a new problem

Means you guys were a little too good. If you kill some waves too quickly, it despawns the rest of the enemies. It doesn’t hurt when you have to defend something, but you are guaranteed a loss in situations where you have to kill a certain amount of enemies.
