Hello! I'm working on a magic mod and the alchemy section is giving me some trouble.
I've made a special brewing stand which is supposed to allow players to stack potion effects into a single bottle. E.g. Combining 2 speed potions will create a potion with speed 2. But it isn't working.
It seems like the crafted potion isn't keeping its NBT number tag. When I drink the potion it gives an effect of "speed 0 with duration 0".
Here are the screenshots of the crafting procedure and the drinking procedure. Would anyone be able to help?
