Adds slow transport belt. For the times you really want to embrace tranquility. Or just rage at the belt delay. It is pink, don't ask me why.
Mods introducing new content into the game.
Augmented or new ways of transporting materials - belts, inserters, pipes!
Nice. Can you add Bob's support so that there are 17 tiers of progressively slower boilers, roboports, trains and assemblers, each one slower than the last?
Sure, the next time I have nothing to do for 3 months :P
But why would you want to have a boiler which is 17x slower than the normal one?
