Hello, i've been working on a mod recently, and that mod implements a custom recipe that only gives the result once there is enough of a specific item in the crafting grid (eg. 3x carrots, 5x potatoes etc..), however after doing some testing, i've determined that the IRecipe match method isn't called if the user right-clicks to add ONE item to an already existing stack, personally i think that should change, i think that there should at least be a method in the IRecipe interface that gets called when the player right clicks to add an item to an already exisiting stack

Mojang designed the recipe system to not work well with stacked items. A lot of assumptions, and things similar to the guide book simply do not work.

If you control the container, you have the inventory change event, but nothing that should be in recipes.

@LexManos Alright, well that sucks, guess i'll have to make my own workbench then
