Enemies Not Spawning In Properly In Archwing Exterminate Alerts

[LifeNine]

In the most recent alert for the Enigma Loki Helmet and many other archwing alerts, the enemies don't all spawn in properly. Before the required enemies are killed, the map tells you to go to extraction. You have to go back through the map to get the enemies to spawn in.

 

In this most recent alert, I was at 36/85 enemies killed before it told me to go to extraction. I went to the extraction point, then I went backwards to get a few enemies to spawn in. I had to repeat this five or six times to get the required 85 enemies.

 

I'm not sure if this spawning problem is exclusive to alerts since I haven't played archwing exterminate missions outside of alerts for a long time.
