Productivity Modules starting level 21 need 2 from the previous instead of 1, whilst providing the same increase then the previous (20%). All other modules just need 1 from the previous. This needs to be fixed, as it just increases the cost of 1 lvl 25 Productivity Module to 680.000 Gold Plates, instead of 7.700 Gold Plates.
Also the pollution generation of these makes no sense. lvl 3 does 10% (vanilla) and your level 4 does 160% more pulltion and it just goes up into amounts that are not feasable at all.You raise the rate by 110% on average, but sometimes only by 10% or some random number. Please get the modules in order so that they are actually useable.
Just for info:
A Furnance Warehouse with max lvl 25 Prod modules, beaconed with lvl 25 Speed modules to reach +80% speed, with max prod, does more then 1.000.000.000.000 Pollution per tick. This colors the world in pollution in a few seconds. And when i mean the world, i speak about 1.000.000 Chunks in each direction. The attack that came at me after it turned that beast on, wiped my whole base from the planet. As there were millions of millions of behemoth biters comming. No way in hell this can be defended. I had more then 20.000 Laser turrets with max walls (even walls block spiters mod installed). You need to rebalance pollution and/or pollution scrubbing OR you add some other way of static defense/walls to your mod.
Like it is now it is not possible to play with high end stuff, if you are not on an island.
