Hi
In my mod these three configurations get corrected on each client launch. event if they are on default...

What am i doing wrong?

[09:03:33] [modloading-worker-0/WARN] [ne.mi.co.ForgeConfigSpec/CORE]: Incorrect key Configs for Futuristic Factories.ENERGY_UPGRADE_STORAGE_EFFECTIVITY was corrected from 1.0 to its default, 1.0. 
[09:03:33] [modloading-worker-0/WARN] [ne.mi.co.ForgeConfigSpec/CORE]: Incorrect key Configs for Futuristic Factories.ENERGY_UPGRADE_CONSUMPTION_EFFECTIVITY was corrected from 0.125 to its default, 0.125. 
[09:03:33] [modloading-worker-0/WARN] [ne.mi.co.ForgeConfigSpec/CORE]: Incorrect key Configs for Futuristic Factories.SPEED_UPGRADE_ENERGY_CONSUMPTION_MULTIPLIER was corrected from 1 to its default, 1. This seems to be an error.

}

 

First, I would use `#defineInRange` instead of making your own validator. Second, I would use the associated config value types like IntValue or DoubleValue (floats don't exist in toml).
