Hey! just giving a heads up that, while the mod works great. The Costs are quite overtuned.
Specificly looking at bobs highter tier buildings. The 20 and 10x multiplier on on heat exchangers and turbines, also applies on the amount of the previous tier turbine/heat exchanger it needs. This makes sense for, tier 1 turbines where you need 10 tier 3 steam engines that havent been made more expensive.
But applying it to every tier leads to the cost being exponentially higher. with a a tier 3 heat exchanger costing 20 tier1 x 20 tier 2 x 20 for 1 single tier 3 exchanger.
Leading a single tier 3 exchanger to cost, among other things, up to ~ 250 000 steel plates , and 350 000 copper plates.
