Situation: attempting to use --excludelist list.txt to download data raised this error:

Situation was resolved by adding the dropped leading zero to the list of member numbers, but anyone's list with the leading zero drop will flag this error. This error may need to be fixed regarding the leading zero's, but also the second line of text is useful for resolving the error and did not display.
