It's very strange that it says all tasks completed, first she should have asked for carrots, after you brought them, at night the event should unlock, and yes, right where it says that nothing is visible, the indicator that the event is there should be her busket. I'm just trying to understand if you could have hit some kind of undiscovered bug)

"Oh! You again... Did you need anything? No? Then I'll get back to my flowers..."
