This is wonderful.
I think blight should still be active though but only if it works differently. It should only affect one crop at a time and only spreading to other crops if they are close enough for long enough , and not just disappear your plants. You should get a warning about your so and so crop looking strange. Which would give you time to fight it off , sort of like fighting a fire.
You should have to decide whether or not you want to battle the blight , let the crop die, keep it from spreading to nearby crops.
