Custom crafting not working with potion as ingredient

CRAFTBOOK-3055 - Reported by cyclo

I'm having an issue where if a recipe calls for a potion in the ingredients, the resulting item does not get made. If I replace the potion with stone, for example, then the recipes crafts successfully. currently using build 3898
