Those changes happened with 1.104; Leadership gives +10 morale for each skill point, and the food bonus' is doubled from what shows up on mouse over.
The bug with morale (no gains from winning most battles) was fixed in that patch as well, which I think was the biggest issue that most of us were having. I think resetting the food bonus back to what it was before would be a good idea, and then we can see how things go from there.
