So i've about 5 settlements made so far with about 1-2 living in the smallest of those. I also have to deal with settlement attacks randomly in which case I have to rush to the settlement to help with the defense.
So this one time, a couple ghouls attacked a settlement but I turned up pretty late and both the settlers living there had died. I was really pissed. I'm hoping they would re-spawn in some days or that settlement will be re-populated again as there are crops that need tending. So, long story short, do dead settlers re-spawn. Or, if not, can new settlers arrive in their place? I'm not that far into the game that I want to keep increasing my settlements. Its a drag to look after so many...
