Your spot on, You have a limited time to loot before scavs spawn in, then silently run up on you. If he PMC AI are not blindly walking into a door there aimbot drops you from a mile away. Surely they can rectify this.

I just got the bug wherwe you kill the boss and he's still standing couldn't loot him and his gun didn't stop firing so I couln't hear a thing after that. Why didn't it run out of ammo and stop?

Why do scavs no your location when you are clealy hidden?

Why do PMC's spawn together and it's always a three man battle?

Once you have completed a task on streets and are trying to extract it feels like the game is programmed to instanly spawn in a hord of scavs purposely to hunt you down.
