I don’t know if it was intended by EA or not, but anyway I fixed the issue where the Superfood Salad from Spa Day (GP02) didn’t appear on the restaurant menu.
It is likely EA will fix this problem in their next patch, but until then this mod will be useful. And, if there is other food that doesn’t appear either, reply to me with the the name of food and I’ll see it if I can fix it too.
