How to change the Metal Bar Price

Go to the config file

zeros_retrominingsystem\lua\zrmine\sh\zrmine_config.lua

At line 230 the Metal Bar Price gets defined

The way the price currently gets calculated is by multiplying PricePerKG with MetalBarWeight

Alternatively, you can right its just like this

The price gets later slightly modified by the npcs Min/Max BuyRate

If you dont want this to happen then just change both to 100
