Some MCR mods write ore generation like this: @Override public boolean canHarvestBlock(BlockState state, BlockGetter world, BlockPos pos, Player player) { ItemStack tool = player.getMainHandItem();

    if (tool.getItem() instanceof PickaxeItem pickaxe) {
        return pickaxe.getTier().getLevel() >= 3;
    }
    return false;
}

that's makes Tinkers' Construct pickaxes unable to mine it. So this mod fix this problem.
