That being said what is good way. The first challenge requires a piece made of 3 pieces @6/ per sec. how to go about achieving that without being able to cross over conveyors?
Wondering if the challenges are meant to make sense without having tunnels available. Without the tunnels,some pieces that are mined and cut become inaccessible perhaps requiring extra hubs to receive unused pieces. As a result getting needed pieces then requires building long roundabout conveyors and then uses up the limited building parts available. Seems like a good game, it’s just not making complete sense.
