This will only work if msg requires one further argument; it only fixes a small part of the problem by brushing over the original error.

To make this more failsafe, you'd have to redesign the whole thing so the placeholder for missing arguments could be replaced by some verbose string. I'll think about it and probably come up with some solution later.

Update: here's the function:

function Nx.prt (...)
    local args = {...}
    local i = 1
    -- replace missing/erroneous placeholders
    function replace_placeholders(placeholder, item)        
        i = i + 1
        if (args[i] == nil) then
            return '[missing argument]'
        end
        if item ~= 's' and item ~= 'q' then
            if type(args[i]) == 'string' and string.match(args[i], '^[.0-9]+$') then
                return placeholder
            elseif type(args[i]) ~= 'number' then
                return '[not a number]'
            end
        end
        return placeholder
    end
    args[1] = string.gsub((args[1] or 'nil'), '(%%[0-9.]*([cdeEfgGioqsuxX]))', replace_placeholders)
    
    local f = Nx.prtChatFrm or DEFAULT_CHAT_FRAME
    f:AddMessage (Nx.TXTBLUE..L["Carbonite"].." |cffffffff".. format (unpack(args)), 1, 1, 1)
end
