I was able to test the "failed to make" part of things with my gimpy fletcher.

It works, thanks! Skillbuilder portion seems to operate fine now (with the changes below), at least for fletching.
However, the recipes.xml file still has the same problem as before (I posted about this in the Make It 2.9.1 thread).
To fix, make the following changes in the Greater Arrows category:
Change the recipes for Greater Blunt Arrow and Greater Frog Crotch Arrow to use Wrapped Bundle of Arrowshafts (original recipe doesn't specify Wrapped), and add the missing recipe for Greater Acid Arrows:
<Recipe name="Greater Blunt Arrow" list="250 Greater Blunt Arrows" use="Wrapped Bundle of Greater Blunt Arrowheads" on="Wrapped Bundle of Arrowshafts" skill="Fletching" diff="??" burden="??" resttype="??" restore="??" cost="??" desc="??" verified="??"/>
<Recipe name="Greater Frog Crotch Arrow" list="250 Greater Frog Crotch Arrows" use="Wrapped Bundle of Greater Frog Crotch Arrowheads" on="Wrapped Bundle of Arrowshafts" skill="Fletching" diff="??" burden="??" resttype="??" restore="??" cost="??" desc="??" verified="??"/>
<Recipe name="Greater Acid Arrow" list="250 Greater Acid Arrows" use="Wrapped Bundle of Greater Acid Arrowheads" on="Wrapped Bundle of Arrowshafts" skill="Fletching" diff="??" burden="??" resttype="??" restore="??" cost="??" desc="??" verified="??"/>
Latte is on it's way.
