Okay, so this is weird. Either a bug or something I didn't know about the KickStarter...

In the Objects data there is LOOT_Kickstarter_Pouch_JoshuaSpice. In the ItemCombos there is LOOT_Pouch_JoshuaSpice. There is no LOOT_Pouch_JoshuaSpice in the Objects data. Given this I'd suspect we need to change the recipe data to use LOOT_Kickstarter_Pouch_JoshuaSpice as that is what you are holding.
