The hostages? Because their pathfinding is absolutely attrocious. Not only are they slow but they too often go in literally every other locaiton except the one they are supposed to go to follow Lona. It takes 10 minutes + just to save multiple women.If you have heal skill taken, you can heal them, but not to the point of them walk on their own. Just heal to crawl faster.
But the enemies? Oh they will follow you to the end of the Earth perfectly while also dodging your attacks. I am absolutely convinced that those hostages simply don't want to leave and we are just forcing them to do it. Fine by me, i am considering not rescuing them at all. More toys for the goblins.
