bad message-id error when downloading article body

[alex]

i don't remember it was here on the forum or email, cannot find it here, i added an option to download such bodies for test purposes in properties->articles - "detect bad message-id", so you can at least see what it is by temporarily unchecking the option, a number of times people mentioned the issue, it might be a server problem which returns wrong or corrupted body or when newspro trying to retrieve by article number (as a last resort) with the header list out of synch with the server (servers were switched) etc.
