Not sure how common this is in the game, but I’m assuming it’s a product of the Random NPCs option and the RNGs wrath.
I was starting up a new character after dying quite a few times due to ineptitude. I got lucky and spawned in an evac shelter that I had stocked food and tools in with a previous character. Good times were had as I trained diligently through the day with construction and the general skill of scowling at rain.
Once night came I was greeted with the sound of a large group of mobs rustling about outside. I decided to wait them out and see if whatever they were would just go away. They did, and at that time i decided on a night raid on the town. When I got on the road those groups of mobs came back at force and followed my jog toward the town. I finally found out what they were when they caught up.

I was accosted by a flood of demands to drop my weapon and to help them kill their mothers before I apparently angered one of them and they decided to promptly pump me full of lead. What even.
