So i think the bug is quite well known by now; for those who don't know, there appears to be a bug which results in the Pip Boy displaying incorrect statistics about your settlement(s). What I would like to know is whether this is purely an information bug or a deeper bug which screws up the settlement mechanics. For instance if your settlement actually has say 40 defense, food and water, but your Pip Boy is showing 0 for all three, would your settlement loose happiness when you are away or is it just displaying incorrect information?
If your defense is lower in Pip Boy then would an attack on your settlement would be more likely? Also can settlers die if your food/water falls too low or does it just result in a lower happiness rating or do they just leave?
