Not sure if this is the right place for this (I couldn't find an "FAQ request" page), but the "Dastard's Distraction" feat is straight up incomplete:
You gain Diversion as a bonus feat. If you already have this feat, you gain a different feat that lacks prerequisites. When you use the Diversion feat to allow multiple allies to hide, you take a –3 penalty to your Bluff check for every ally after the first, and on a failed check. You gain a bonus to Bluff checks to create a distraction equal to any attack roll bonuses you have that specifically apply to resolving dirty trick combat maneuvers. You must have Improved Combat Maneuver (dirty trick) to select this vanguard discipline.
What? What happens on a failed check?! The suspense is killing me!
Pretty sure that's a copy paste error.
Diversion says 'but you take a –5 penalty to your Bluff check for every ally after the first, and on a failed check no ally can attempt to hide.'
It probably was the rest of that sentence and only partially deleted.
