Can't change UU cost of ender pearl (or any item)

  • Hi guys. I tried to change the cost of ender pearl and iridium in the ic2.ini file. Changed the values but the items still costs the same.

    Is there some setting I am missing here?

    This is what I have changed in the ic2.ini file:

    [balance / uu-values / predefined]

    IC2:iridium_ore = 1

    IC2:iridium_shard = 1

    minecraft:ender_pearl = 1
