I kind of regret restarting my game and making a base out on top of a mountain. Its kind of so immersion breaking when scouts magically spawn in the middle of my massive settlement. There are so many bodies littered all over the place.
I am considering just moving my base back into caves and just dealing with the bats. Especially since now I know I can just put NPCs on survivor mode and they don't take damage and won't fight back.
Also I built bears traps / small animal cage traps for the first time and holy heck they catch so many animals. Didn't realize that they just randomly spawned in animals at certain intervals, thought the the traps were going to be really useless at first since I assumed they would be realistic and only catch animals that walked over them when the game first loads. But nope free animals popping into existence out of thin air once the trap is out of sight after a short cool down.
