generally if people are making mod packs that do generic modifications to things they would be responsible to tune everything they effect and it would be outside of my control.
if you could provide an example mod configuration file or some way to replicate the issue i could have a look at it.
Burn value is not something i can't remember off the top of my head what it is set to but i will have a look at it.
FYI i start a 10 day cruise in a couple of hours i am bringing my laptop but low probability i will look at this while on the holiday.
Adding a config option to set values for everything would be a nice addition for people to tune cost / HP / everything to whatever they want i agree.
