Legendary feature! Because it has been requested for so long, but it wasn't until now I had the chance to do this right. Now, when trying to craft an item with missing ingredients, it will indicate which ingredients are missing.
IMPORTANT: Due to the Event Relinking fix, you need to restart your active Scenarios in order for the fix to work. This is highly advisable before moving forward with the current save (damage caused by this bug is irreversible, otherwise a proper migration would have been implemented).
