These guys have been bugged for a long time. At the end of each lap, they seemingly freeze in place. When you continue on, all of a sudden your stealth will be restricted, and the boss will appear out of nowhere. These guys have the ability to one shot my character, and half the time I don't have any stamina to break free from their attacks, because I was running about and there was no threat to contend with. Its really not fair to get killed by an enemy that wasn't there a second ago, and just teleported through a glitch to kill me. WHy can't they just walk in perpetual laps, so their movements can be traced? There's no reason why they should appear out of nowhere and kill people. Please fix this. It's gone on for way too long.
