its annoying that the things empty when you move them and that everything detaches. i wish that the cords stayed attached and the contents also stayed and there was a "store" button that actually stored the piece and emptied it instead. the way that it is accidentally wasted material and also its extremely tedious to re-route or re-configure your logistics. im still playing and just unlocked the big gems but so far thats my biggest criticism. group select would also be nice.
