Game is broken about food

Once you expand your nation a lot, it becomes impossible to cover the food demand.

I know the tips : max food prod, build infrastr + fortif. on food provinces, put troops on food provinces, no more units...

But it's impossible to come back positive on food.

And once your stock is at 0, you lose lands : you cannot expand any more.

What is the point having to take the same provinces day after day ?

Where is the pleasure in this ? Do you call it a game ?

Sugg : a province taken is definitely taken. Delete this absurd revolt system.
