Oh my god. Can you go a little more in depth? Was the problem something along 
the lines of `treu` typo, or a non-existent flag? Is that at all salvageable? I

Also, I can't attend to this issue immediately -- replying on the phone is one 
thing, but almost any other action is out of my reach for the next couple 
days/weeks.
