You can see this issue in action if you craft all available Boom Pop Dynamite. For example, you own 8 Soda, craft 4 Boom pop dynamite, then immediately after you will see you have enough ingredients to craft 2 from the 4 you have and on until you run out. This makes the recipe unsafe to craft unless you drop your BP Dynamite on the ground before you start crafting.
