I'm not sure if anyone else is sharing this problem, but for some reason settlers like to stand in doorways and block entrances.Just thought I would put this up here so maybe on day it might get fixed.
Something else I've noticed, this one is a cosmetic feature. I noticed even when I am under cover from rain, droplets still drop onto my Power suit visually when in first person. I'll Put anything else I find on here and keep updating this post.
P.S Fallout 4 is one of the greatest games ever so far, I can't get myself to play any other game. Thank you very much, and keep up the great work!
