It looks like the "Max" number of available crafts is being determined by only the last listed ingredient rather than the limiting ingredient, but also incorrectly so. Examples:
Mead Base: Frost Resistance Honey 210/10 Thistle 208/5 Bloodbag 71/2 Greydwarf Eye 505/1 Max: 50
Mead Base: Tasty Honey 210/10 Raspberries 264/10 Blueberries 193/5 Max: 19
Raw Fish Perch 117/1 Pike 4/1 Trollfish 1/1 Max: 3
Troll Hide Cape: Troll Hide 72/10 Bone Fragments 504/10 Max: 50
I am using AzuCraftyBoxes, but also tried moving ingredients to my inventory. The listed max remained incorrect, although would sometimes change. Recipes with a single ingredient seem to be more reliable.
