It's a shame you never figured out what exactly was happening.
Do you want to leave the debugging messages that say "unhandled redirect"? I have been approached by some people who are troubled by those; thinking that there is a problem with their mafia. I've reassured them of course, but it might be nice to not need the reassurance.
I figured once Veracity posted about questlog.php that they were running (probably a relay) script involving Manuel.
