I've now been getting the settlement glitch a lot lately as well, Sanctuary keeps saying 16 people instead of 19 and the resources aren't there so everyone's getting unhappy. The annoying problem is that happiness seems to drop much faster than it rises. I know before it was glitching the happiness was in the mid-80s, now it's always 60's-low 70's.
Another settlement glitch I just noticed is settlers continuously taking more and more guns from the workshop. I spoke to Sturgess yesterday and he had 17 combat rifles and 5 short combat rifles! The 🤬?! I'm going to have to go around to every settler and get all my guns back and start putting them in a steamer trunk. I was already putting my good stuff and any Legendary items in seperate metal boxes. Very annoying.
I also had a Super Mutant attack on Sanctuary for the first time since building the perimeter fence. A couple spawned inside and the rest were taken care of outside. However the framerate (on PS4) was incredibly real until every last enemy was killed. I could barely run around it was so bad.
