Modpacks break Create recipes. This fixes them.
When you run Create alongside addon mods, you often end up with two or more recipes that accept the same input. Two mods both add a crushing recipe for Blackstone. Three mods each add a different way to mill Wheat. Create has to pick one, and it picks essentially at random based on which recipe loaded first. You get whatever the load order decided, with no say in it.
Create Recipe Picker gives you the say. Open an in-game screen, see every conflict on your world, and click the recipe you want to win. Your choice persists per world and applies to every machine of that type.
Run the command:
/createrecipepicker
A panel opens listing every recipe conflict detected on the current world. Each conflict shows the input item and the competing recipes as rows. Click a recipe to make it the winner. Click it again to clear your choice and go back to Create's default behavior.
That's it. Place a crushing wheel, drop the input in, and the recipe you chose is the one that runs.
/reload.
