I have been unable to get this to consistently occur.

What is the expected output? What do you see instead?

CODE:
AsdfWM.Asdf_SendWho = function( msg )
    local wholib = wholib or LibStub:GetLibrary("LibWho-2.0",1);
    if wholib then
        wholib:AskWho({query = msg, queue = wholib.WHOLIB_QUEUE_QUIET, callback = AsdfWM.onEventWhoListUpdated })
    else
        Asdf_Println("Old SendWho");
        SendWho( msg );
    end

       When the problem occurs, "Old SendWho" will continue to print, wholib will continue to be empty.

What version of the product are you using?
2.0

Do you have an error log of what happened?

Please provide any additional information below.
