I, for one, would certainly like to know more on this as well. Especially whether or not paths/queue's can be saved to a blueprint. In Planet Coaster because paths and queue's could not be saved to blueprints I rarely subscribed to anyone's blueprints in the workshop. Needless to say that there were many blueprints that I would have loved to subscribe to but the difficulty of guessing where the queue's were supposed to go wasn't enjoyable.
