I've got two villages rolling along smoothly now on the normal setting so thought i'd give myself a challenge with my first village on the hard setting. Just wondering--does harder mean you just get dumber villagers? I can't seem to get any of these guys to stay on task, they keep switching around or wandering off, feel like I'm babysitting! "Get back to that research table or you're all gonna starve!!!!"

Should I expect this level of intelligence from all further offspring on this island?

yes in hard its like they have no brains

Thats why they call it "Hard" You gotta babysit them more, and do what some others (BB) like to say "Crack the Whip"
