Paranormal display.newGroup():insert() function bug activity

I have noticed strange bugs with display.newGroup():insert() function.

I had this function:

function orderObjects(field)
    orderGroup = display.newGroup()
    
    local main_obj = {}
    for i = 1, field.ROWS do
        for k = 1, field.COLS do
            if field.cells[k][i].object then
                if field.cells[k][i].object.type ~= "main" then
                    orderGroup:insert(orderGroup.numChildren + 1, field.cells[k][i].object.image)
                else
                    main_obj = field.cells[k][i].object
                end
            end
        end
    end
    orderGroup:insert(orderGroup.numChildren + 1, main_obj.image)
end

I cannot comprehend the complexity you are introducing, but a simple suggestion, why do you *not* check as

1
2
3

if main_obj.image ~= nil then
  -- do the inserting here
end
