If your objective tracker is giving you a different instruction, please let me know, and I'd be happy to help. :)
The optional Leather Crafting path in the Burthorpe book does give the wrong instruction currently. It gives the 3rd step first (Hat It Forward - Craft soft leather from your backpack into a leather cowl) instead of the 1st step first (Steak Your Claim - Collect cowhide by killing cows). I've already sent in an in-game bug report for it and a few other minor things I've come across while making new accounts and going through the various path options (working on cleaning up the Achievement Paths wiki page ;D).
Another one to look into is the Mining & Smithing path (Burthorpe book) - The last step asks you to equip the bronze helm while you have a bronze dagger equipped, but it doesn't trigger after equipping the helm; you have to un-equip and re-equip the dagger while weaing the helm. Similarly in the Weave Your Magic path, the same can happen with the wand and air runes, where it won't trigger after equiiping the wand and you need to equip the wand, drop the air runes, and pick them back up.
