I just finished planting 5000 flowers over 3 hours and after it said I discovered 7 expeditions, it suddenly lagged, crashed and I didn’t receive any rewards or expeditions 
Can anyone tell me if there’s a way to reload it?
Based on my experience, if the app crashes during flower planting, restarting the app will resume the flower planting session (though petals will still be consumed during the restart process).
Therefore, please initiate the query from the app side.
