Monochoes

Maybe it also has something to do with all the reloading of saves i've done after the quest ended in failure or during the combat, hard to tell. And note that neither the npcs nor the main character is in combat mode, so I don't think the cause would be some enemy got spawned under map.

I'm running The Outer Worlds 2 on PC, during the quest Pinching The Pupa, a wave of enemy never spawned, I've fought the first wave and the second, not sure whether it's the third one missing out or the fourth one, so the quest ojective stuck on helping to defend the fort with no enemy to fight with, which you may see from my attachment below, the radar is clear. Before doing the quest, I wandered into the nest of Mantisaur and picked up the pupa before hand, not sure if it's related. I've tried reloading saves, exiting the game, yet nothing seems to be of help. Besides that bug, there is also annoying stutter of sound effects reloading or loading into a different map like all the sound effects got loaded and played loudly in one second.
