im directly saying the problem, sapphire from ice and fire wanted by a villager, and you unified the sapphire to biomes op's sapphire, and that villager doesn't accept bop sapphire, he wants ice and fire sapphire. please help this.

add gemSapphire to the blacklist in the config file

but i want it be unified. i don't want 2 different sapphires. i'm playing it as it is at the moment, and hope you provide a fix that will let me choose which gem be the basic one.(ice and fire's sapphire instead of bop sapphire)

then add the modid from ice and fire to preferredMods

but won't it unify all the things from ice and fire? cus it has also silver ingot, silver nugget, etc
