-- What is the nature of the defect?

When trying to queue 1 Magnificence of Leather, GnomeWorks puts 100 Sha-touched Leathers (at 2g each, to make 20 Exotic Leathers) in the shopping list, instead of 20 Exotic Leather (which are cheaper to buy at 4g each). Same happens when trying to queue Magnificent Hide, it queues Sha-Touched Leather instead of Exotic Leather. Other recipes work fine tho.

-- What (if anything) triggers the defect?  (happens when loading, when activating the mod, when clicking a particular button, etc)

Simply load the addon. The price is being calculated by Lil Sparky's Workshop.

-- Please post any error messages associated with the defect.

No error whatsoever. I'm using GnomeWorks with Lil Sparky's Workshop and Aki's Recipe List. Using Auctionator for AH scan. I tried clearing saved variables from all these addons and did an AH rescan, but the problem persisted.

This is a known shortcoming of the current (incomplete/alpha) code, it doesn't calculate the cheapest path correctly. However, I do believe this is the first actual bug report for this, instead of just a comment on the main page :)

Ah, well. Glad to help then :)

yeah, calculating the cheapest path is quite complex.  but something worth noting is that you can alter the recipe selection process right in the queue by right-clicking an entry.  you see, when gw adds items to the queue it actually adds all possible recipes/sources for each item.  the one it favors follows a priority that can be adjusted by the user for each item.

the auction scanner module was supposed to be useful for finding the cheapest ways to craft things, but i'm not sure it's terribly well designed.  if you have it open, you can filter your scanner results based using the queue list.  it's all supposed to work in concert, but the code was never added to do things automatically.

finally, you can black-list individual recipes and add preferred recipes in the reagent frame of the main window.  it's some form of right-clicking (with shift i believe) to assign preferences and blacklists.  this would be an easy way to make the above adjustment -- have it prefer exotic leather.  don't blacklist sha-touched, tho, or it will always ignore that conversion.

btw, i'm glad to see the project still lives.  big thanks to wildcard and others for keeping things alive.
