I didn't want this to get buried in another thread so I started a new one for this admittedly minor error. The skill Use Rope has been eliminated entirely in the Pathfinder rules which is fine by me. For the Escape Artist they have taken this into account with a new method used for determining how difficult a knot in a rope is to bypass. However under the rules for grappling hooks in the Equipment section it seems as though the rules were lifted straight from the 3.X PHB with no editing as it still requires a Use Rope check.
Oh and also everyone else seems to get two Perception bonuses based on Keen Senses except for Halflings. Let them have a bonus to taste!!! Not really errata I know, I'm just a fan of making Halflings more like earlier editions of D&D's versions which is something that Pathfinder has addressed somewhat.
