What you want is the bugged buff duration.
Gourmand running out during long duration crafting is a feature. If you want permanent morale pick stylish/optimist. If you want burst morale regen after a fight, or stats/speed before a fight, along with higher stomach capacity and eating speed, pick gourmand.
Gourmand was never supposed to give you the permanent benefits of 8 stat points and quick for two chargen points (hello brains, how are you?).
