The text of the trait is thus:

Shadowhunter (2 RP): Characters with this trait deal 50% weapon damage to incorporeal creatures when using non-magical weapons (including natural and unarmed attacks), as if using magic weapons. They also gain a 2 bonus on saving throws to remove negative levels, and recover physical ability damage from attacks by undead creatures at a rate of 2 points per ability score per day (rather than the normal 1 point per ability score per day). Dwarves can take this trait in place of their bonus feat, also gaining Iron Will as a bonus feat.

My problem with this is that dwarves do not get a bonus feat. Is this a module specific thing? Did paizo just screw up?

edit: I quoted this from d20pfsrd.org, maybe they got this wrong? If anyone has the relevant text from an actual book they can quote me I'd appreciate it.
