It is a massive oversight. Like, they were worried there were more raiders, so they are all going to move out (of a very defensible spot by the way!) and become drifters again, easy pickings. Then you kill the rest of the raiders, and it's a dead end back that way without boats, so all their problems are solved. Yet they don't acknowledge it, and still plan to just leave and die outside. This is absurd, no half-sane person would do that, especially given their lack of combat inclination/equipment. They should be happy to know Paige is dead, and either stay in GMS or take over his camp. How cool would it be if they re-established their community, even had an option to ally with SGS and maybe get a trader or two! Wasted opportunity, I get that this was an early thing and y'all wanted to get on with writing the latter parts of the game, but it's a massive plot hole that a huge proportion of players will encounter. Not to mention a very easy fix if you're minimalist about it, just a "Thanks, maybe we'll stick it out after all" and add nothing else, I'll be happy.
