I am loving the game but I wish the auto extraction timer was longer. sometimes there are extra elites or chests way way past the last objective. 

The worst offenders in this are the escort missions where the troops extract and you have a room full of enemies and a big chest in the back. sometimes you can swing wide and avoid the troops leaving sometimes you risk their deaths swinging wide, sometimes it all works out.

I know it's a lot to ask but if the timer was longer or if you could just hang out and search after it's done and let the other leave that would be wonderful. 

Numerous times everyone is ready to leave immediately and there is a hoard to cleanse! I'm new so chests and more enemies means more loot for me that I very badly need. does anyone else feel like me? maybe I miss the point of the short auto extraction feature.
