I made a shelter out of my… shelter. Built a fireplace, have crap laying around all over, etc.
I play with NPCs on (because otherwise you have literally useless skills in the game). Two guys walk in. One wants to rob me, the other isn’t hostile. I killed the hostile one, while meanwhile his buddy walks behind me and starts grabbing 2 of my firearms and some weapon mods.
He runs out the door. I run over, grab my AR-15 sitting there (loaded, natch), and light his ass up.
I get a -75 Morale penalty for killing an innocent.
I don’t know how it would be done, but we really need some kind of designation for “This is my area”. That survivor stole things that I went out and scavenged, and then I get a shitty morale penalty for dealing with the situation.
It’s rather like when you get them to join you - they just steal anything they want of yours and you have to TRADE for it back. It’s silly.
