I have never bothered 'migrating' to another area before ( apart from the tutorial ), just expanded my borders, but I want to cover some ground quickly and grab a mountain region for ore. The problem is that I've completely forgotten how the migration carts works. I have built and filled the cart, sent it off to the area I want to claim and then 'released' the goodies inside. The problem is my pioneers are just expanding the land and not actually building the buildings I have requested. Can anyone suggest where I might be going wrong, please ?
