I'm not sure if this is a bug or not, but while I was in Ratchet, I was being attacked by horde, and the guards were not doing anything.
There was also a horde hunter that was unflagged, following me along while I was running up to Ratchet with his pet on aggressive so it would continue to attack me. This wouldn't have been a problem as the hunter was only lvl 19, but his pet, nor the hunter, was being flagged by his pet attacking me. And since hunter pets run at 200% speed or so, you can't get away from them.
The hunter's name was Justinbieber.
