when you're crafting honeybuns, it prefers to take 35 from a stack of 50, so you end up with an inventory full of stacks of 15 flour which will only be used once you have no more full stacks.
It'd be nice if it prioritised using smaller stacks up to free inventory space. It's certainly nothing major but it's annoying none the less, especially when you're crafting so many, I imagine the same thing happens with any recipe that uses less than .50kg of flour.
