On Gauntlet and any other option that has you going through a set path to hit enemy NPCs, after a while the enemy mechs stop responding. They just stop.
What may trigger this:
- Quick fire hitting the NPC even before the enemy mech is activated to shoot you
- Quickly toggling target ® between enemies
- Killing all enemy mech spawns on a specific position
Also, is it supposed for the Quick Fire to have no end? Over 25 rounds and it's still going.
